The fallopian tube is described as having four parts (lateral to medial); Fimbriae finger-like, ciliated projections which capture the ovum from the surface of the ovary. Of these, only about 500 will be ovulated during a woman's reproductive lifetime. It is part of a system that directs many bodily functions: the limbic system. The dominant follicle continues to produce estrogen. The vulva consists of the following structures: The mammary gland is a modified sweat gland and is an accessory gland of the female reproductive system called the breasts of females. The thin, perforated hymen can partially surround the opening to the vaginal orifice. It has a large variation of positions within the pelvis, described by its degree of anteversion or retroversion, and anteflexion or retroflexion. Procedure for CBSE Compartment Exams 2022, Maths Expert Series : Part 2 Symmetry in Mathematics. It secrets sex hormones like oestrogen and progesterone. Two hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH), are released from the. READ MORE. As a fetus grows, a womans body will prepare for the birthing process, which includes the widening of the pubic symphysis, a joint between the two pubic bones. The number of eggs you have continues to decline as you age and menstruate each cycle. The female reproductive system includes ovaries, fallopian tubes, uterus, vagina and vulva. Monthly, follicles are stimulated by two hormones, the folliclestimulating hormone (FSH) and LH, which stimulate the follicles to mature. How the female reproductive system works. Because carrying a child and giving birth is such a delicate process, numerous physical problems for the mother can arise. Altogether, three ligaments hold the ovaries in place and these are: The ovary contains a number of small structures called ovarian follicles. As estrogen levels rise, like a switch, it turns off the production of follicle-stimulating hormone. Both the hormones support the endometrium until conception takes place or the cycle starts again.

They catch the oocyte when released from the ovaries. It facilitates the passage of sperm whilst maintaining a sterile environment in the upper female reproductive system. The capsule is a fibrous connective tissue called tunica albuginea. During the menstrual cycle, a female ovary develops an egg and then the female body prepares for pregnancy. Egg-producing physiology. After fertilization of the ovum and sperm, these tubes transport the fertilized egg to the uterus for implantation. We also use third-party cookies that help us analyze and understand how you use this website. This estrogen is responsible for the growth of the endometrium. It is a type of disorder that causes irregular or prolonged menstrual periods and sometimes leads to increased androgen levels. Ovaries become unable to release eggs regularly and develop small cysts. Further, each ovary weighs only about 68 g and is about the size of a walnut. Solution: Two major functions of each are as follows: once it has entered the female reproductive tract. The major organs of the female reproductive system include: When properly fertilized with a mans sperm either through intercourse or artificial insemination a womans egg carries all of the necessary material to produce children. These hormones include: This phase starts on the first day of your period. Elsevier Saunders. Once in your uterus, the fertilized egg can implant into the thickened uterine lining and continue to develop. They allow the secondary oocyte to complete the cell division and form an ovum. During the follicular phase of the menstrual cycle, the following events occur: The ovulatory phase (ovulation) usually starts about 14 days after the follicular phase started (the exact timing varies). Ovaries are also engaged in producing sex hormones, which are oestrogen and progesterone. As a result, they stop growing and die. If intercourse has taken place and sperm has fertilized the egg (. Not needed to support a pregnancy, the lining of the uterus breaks down and sheds, and the next menstrual period begins. The uterus, commonly referred to as the womb, is the location of normal implantation of an early embryo. This is where fertilization occurs. Ovulation is a physiologic process defined by the rupture and release of the dominant follicle from the ovary into the fallopian tube where it has the potential to become fertilized. With every cycle, a woman's body prepares for a potential pregnancy, whether or not that is the woman's intention. The female reproductive system functions to produce gametes and reproductive hormones, just like the male reproductive system; however, it also has the additional task of supporting the developing fetus and delivering it to the outside world. The dominant follicle continues to produce estrogen. The female reproductive system is designed to carry out several functions. Unlike the male reproductive organs, the female reproductive organs are located mostly in the pelvic cavity. The external genitalia includes the mons pubis, labia majora, labia minora, clitoris, and structures associated with the vestibule. The vaginal artery plexus is also known as the vaginal venous plexus. The remnants of a large ruptured follicle become a new structure called the corpus luteum. The primary function of the ovaries is to produce an egg or ova each month. Its primary function is to supply blood to the lower section of the body. READ MORE. Histology: The ovaries are covered by a simple cuboidal epithelium called the germinal epithelium on the outside. The ovulation process is regulated by fluxing gonadotropic hormone (FSH/LH) levels. This zygote eventually becomes a fetus. If you have any queries on this article or in general about Female Reproductive System, ping us through the comment box below and we will get back to you as soon as possible. Moreover, it is anterior to the rectum and posterior to the urinary bladder. The vulva refers to the external female genitalia. Uterine tubes, also known as oviducts, are the part of the female reproductive system that carry ova from the ovary to the uterus each month. In humans, internal fertilization takes place. Structure: Vagina is the female copulatory organ of the female reproductive system. The cervix or the neck of the uterus protrudes out through the anterior wall of the vagina. The female reproductive anatomy includes both external and internal structures around the female genitalia. Many people call the days that they notice vaginal bleeding their period.. It is almost cylindrical, and it changes at the time of pregnancy. Reproductive physiology in the female lizard is broadly similar to that of the avian patient. Ovaries #2. The pelvic region is the area between the trunk and the lower extremities, or legs. The female reproductive anatomy includes parts inside and outside the body. These hormones (FSH and LH) also trigger an increase in the production of the female hormone estrogen. Infundibulum: A funnel shaped opening to The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections at the end of the fallopian tubes, through which READ MORE Sagittal Cross-section Placenta generally helps exchange nutrients, oxygen and waste products between the embryo and the mother.

This prevents the fertilization of eggs by sperm and thus the implantation of a fertilized egg. Goyal, Mere Sapno ka Bharat CBSE Expression Series takes on India and Dreams, CBSE Academic Calendar 2021-22: Check Details Here. The isthmus is the narrower part of the tube that extends towards the uterus. The uterus is a hollow muscular pear-shaped organ of the female reproductive system which is narrow both anteriorly and posteriorly. These eggs are then transported to your fallopian tube during ovulation where fertilization by a sperm may occur. However, your vagina is its own structure located inside your body. Sex cells - eggs & sperm. They produce gametes and help in the secretion of hormones, which regulates the gamete formation and secondary sexual characters in females. Policy. Fallopian tubes are divided into four sections: Fimbriae: Finger-like projections, entry point of the ovum into the fallopian tube when it is ejected from the ovary. In this article I am going to represent cow but you may also learn other female animals reproductive system. The female reproductive tract is all located within the pelvis. The Graafian follicle manufacture estrogen. The hormones stimulate the growth of about 15 to 20 eggs in your ovaries, each in its own shell, called a follicle. ; Infundibulum funnel-shaped opening near the ovary to which fimbriae are attached. Females are born with immatureeggs. Youre considered to be menopausal when youve gone an entire year without a menstrual period. Embiums Your Kryptonite weapon against super exams! These fimbriae projects over the ovaries with the longest of the fimbriae called ovarian fimbriae that attach to the superior aspect of the ovum. As the follicular phase progresses, one follicle in one ovary becomes dominant and continues to mature. The hymen is a thin mucosal membrane present in front of the opening of the vagina. Part 1 - The Basics. Male Reproductive System. The ovulatory phase is the second phase of your menstrual cycle. The female reproductive system consists of structures that produce eggs and secrete female sex hormones. Contact your healthcare provider if you have concerns about your genitals or have symptoms that concern you. They form the first part of the female reproductive system. They sit laterally to the uterus, and closely adjacent to the fimbriae of the fallopian tubes. The ovary is generally divided into an outer cortex and an inner medulla. The medical information on this site is provided as an information resource only, and is not to be used or relied on for any diagnostic or treatment purposes. The vagus nerve is the longest of the 12 cranial nerves. SOURCES: National Institutes of Health. The fertilized egg then moves to your uterus, where the uterine lining has thickened in response to the normal hormones of your menstrual cycle (also called your reproductive cycle). The PITUITARY GLAND SECRES the FSH and LH hormones, whereas the ovaries secrete oestrogen and progesterone hormones. The oviduct stretches out from each ovary to the uterus. The hymen is very vascular and may bleed when it ruptures, which happens in about 50% of women during their first experience of sexual intercourse. (Menstru means "monthly.''). There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle: follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone. The medulla is an inner, loose connective tissue. As compared to labia majora, Labia minora is thinner and more pigmented skin that extends medially to the labia majora. Women or people AFAB of reproductive age (beginning anywhere from 11 to 16 years of age) experience cycles of hormonal activity that repeat at about one-month intervals. It provides both space and nourishment to the developing baby. The uterus undergoes a periodic shedding after puberty in the female, which is called the menstrual cycle. This dominant follicle suppresses all of the other follicles in the group. Duringpuberty, theeggsmature andovulate. Also during this phase, there is an increase in the amount and thickness of mucus produced by the cervix (lower part of the uterus). It is a thin, circular layer of tissue that, The anterior inferior ligament and the anterior ligament of the lateral malleolus are also known as the anterior tibiotalar ligament. Does Menopause Make Ovarian Cancer More Likely? These hormones (FSH and LH) also trigger an increase in the production of the hormone estrogen. Altogether, the female reproductive system consists of the external genitalia and internal organs. It includes the vulva, vagina, cervix, uterus, oviducts and ovaries (Figure 1). The human female reproductive system is a complex system, which consists of ovaries, oviducts, uterus, external genitalia, accessory glands. Its primary function is to supply blood to the lower section of the body. The vagina has no glands but remains lubricated by cervical mucus and secretions from the epithelial cells. Female. This phase starts on the first day of your period. The femoral artery is one of the major arteries in the human body. The endocrine system controls the complete process of the menstrual cycle. The male pelvis is different from a females. The vagina is the receptor for the penis during coitus or sexual reproduction. The cells ripen on a regular basis, but only one is released each month until a woman reaches menopause. As the follicular phase progresses, one follicle in one ovary becomes dominant and continues to mature. It contains numerous blood vessels, lymphatic vessels and nerve fibres. Vagina also provides an elastic passage for the baby during childbirth. The vaginal artery is said to come from either the uterine, The vaginal plexuses are two arteries that are on either side of the vagina. The organs in the female reproductive system are divided into external organs and internal organs. The functions of the vagina are to receive sperm from the penis during sexual intercourse. We can find these paired, almond-shaped ovaries on either side of the uterus. The average duration of human pregnancy is about nine-month or 38 to 40 weeks. It produces the female egg cells necessary for reproduction, called the ova or oocytes. The vagina is one of the most important and versatile structures in the female reproductive system. In females, the mammary gland is functional and begins to develop after puberty in response to the release of oestrogen. As the egg is released (a process called ovulation) its captured by finger-like projections on the end of the fallopian tubes (, For one to five days prior to ovulation, many women or people AFAB will notice an increase in egg white. They help in the movement of the egg from the ovaries to the uterus. Also, it functions as a birth canal at the end of pregnancy. It provides a passageway for the birth canal at the time of parturition. Found an error? Female Reproductive Anatomy. The internal organs include the vagina, cervix, uterus, fallopian tubes and ovaries. If the egg is not fertilized, it passes through the uterus. The fertilised egg is transferred to the uterus. They are oval in structure and are about 1.5 inches long on either side of the uterus in the pelvic cavity. The hormones stimulate the growth of about 15 to 20 eggs in the ovaries, each in its own "shell," called a follicle. Isthmus #3. The function of your external genitals are to protect the internal parts from infection and allow sperm to enter your vagina. This shedding prepares the uterus to nourish and protect a fertilized ovum. The term menstruation refers to the periodic shedding of the uterine lining. This transport is aided by the peristaltic movement of the muscles and the rhythmic movement of the ciliated cells. Together they comprise the female reproductive system, supporting sexual and reproductive activities.The external genital organs, or vulva, are held by the female perineum.These are the mons pubis, labia majora and minora, clitoris, vestibule, vestibular bulb and glands.The vagina, By the time you reach puberty, only about 300,000 remain. Among these hormones are the estrogens, which include estradiol, estrone, and estriol, with estradiol being the most abundant. The inner layer is of simple columnar epithelium that has cells with minute hair-like structures called cilia. Sexual reproduction involves the formation and fusion of gametes. The average interval of the menstrual cycle is \(28\) days. The cervix is the lower part of the uterus, just superior to the vagina. If intercourse has taken place and a man's sperm has fertilized the egg (a process called conception), the fertilized egg (embryo) will travel through the fallopian tube to implant in the uterus. These cookies do not store any personal information. The endometrium is further divided into their layers with the upper layer that thickens during the first half of the menstrual cycle. The process of giving birth to a baby starts with mild uterine contractions. It is a small protruding structure that comprises erectile tissue and several nerves and blood vessels. This is the process of formation of a baby. The inferior (temporal) horn is the largest component of the lateral ventricle.It begins at the posterior end of the central region, and runs anteroinferiorly into the temporal lobe.. This careful balance of hormones allows the body to limit the number of follicles that will prepare eggs to be released. Structure: Oviducts or fallopian tubes are the two tubes where normally fertilization occurs. At birth, there are approximately 1 million to 2 million eggs; by the time of puberty, only about 300,000 remain. When a sperm meets an egg, it can fertilize it and create a zygote. In such a case, it is released into the peritoneal cavity. The fallopian tubes connect the ovaries to the uterus, and therefore have the function of transport of the ovum towards the uterus. It has a thin wall with the folded luminal surface, and the fertilization occurs in this lumen. It is elastic and muscular with a soft, flexible lining. After fertilization, the secretions of the tubes provide nutrients to the zygote. The upper end of the vaginal canal surrounds the external os of the cervix and produces a recess called the vaginal fornix. Every month, one oocyte matures and is ovulated out from the follicle. The ovaries also produce progesterone, inhibin, and relaxin. Mammary glands only produce milk after childbirth. Externally, the uterus is divided into three parts, the fundus, the body, and the cervix. The major function of vagina is to carry menstrual fluid out of the body. The external organs in the female reproductive system are collectively termed, vulva consisting of labia majora, labia minora, clitoris, vaginal orifice, vestibular gland, and hymen. The endometrium is the innermost layer that is composed of columnar epithelium provided with a large number of mucus-secreting tubular glands. We use cookies to improve your experience on our site and to show you relevant advertising. The umbilical cord is a tube that connects the foetus to the placenta. Hall JE and Guyton AC. At each end is a cervical os, a narrow opening into the uterus and vagina either side. Every month in a menstruating woman, one or two Graafian follicle release an oocyte. Get useful, helpful and relevant health + wellness information, 9500 Euclid Avenue, Cleveland, Ohio 44195 |, (https://www.healthdirect.gov.au/female-reproductive-system), (https://www.merckmanuals.com/home/women-s-health-issues/biology-of-the-female-reproductive-system/menstrual-cycle). It consists of primary reproductive organs and external genitalia such as the ovaries, oviduct, fallopian tubes, uterus and vagina. The hypothalamic releasing hormone, gonadotropic hormone (GnRH): This hormone stimulates the anterior pituitary to release sex hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). the fimbriae, infundibulum, ampulla and isthmus. Fimbriae sweep over the ovaries and collect eggs. Ampulla #4. In addition to allowing a person to have sexual intercourse, it also helps a person reproduce. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone.The uterine cycle governs the preparation and maintenance of the lining of the The fallopian tubes are located in the pelvis and function to transport eggs from the ovaries to the uterus. Like ovaries, these are also present in pair. There are many ligaments of the female reproductive tract which support the organs of the female reproductive tract and also act as a conduit for neurovascular structures supplying these. The paired ovaries produce the female gamete, the ovum. Vestibular glands (Bartholins gland) are small pea-sized glands with ducts opening into the vestibule. It is the primary organ where implantation takes places. In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle. These are present on either side of the vaginal opening. Your ovaries produce eggs. During fertilization, the spermatozoa travel through the tube towards the ovum and fertilization usually occurs in the ampulla. The ovulatory phase (release of the egg). The accessory or secondary reproductive organs are those organs that facilitate the process of fertilization and implantation, support the growth and nourishment of the foetus but do not produce hormones. Altogether, the external genitalia is known as the vulva. The reproductive systems primary goal is to keep a species alive. With every cycle, your body prepares for a potential pregnancy, whether or not thats your intention. The female reproductive system is composed of highly specialized organs which are in a state of constant change, from the sequential alterations characteristic of each menstrual cycle to the dramatic changes that occur during pregnancy. Infundibulum #5. Since the ovary has no direct contact with the uterine tube, it is possible that the fimbriae will not pick up the oocyte. The secretion of these glands helps to keep the vagina moist. The fallopian tubes, also known as uterine tubes, oviducts or salpinges (singular salpinx), are paired tubes in the human female that stretch from the uterus to the ovaries.The fallopian tubes are part of the female reproductive system.In other mammals they are only called oviducts.. Each tube is a muscular hollow organ that is on average between 10 and 14 cm in length, with However, it may also rupture from an injury or during activities such as sports.

Once it releases its egg, the empty follicle develops into a new structure called the corpus luteum. Lets discuss each part in detail. How an egg is directed into a uterine tube. The bacterium can form stationary films on top of surfaces, including urinary catheters. By visiting this site you agree to the foregoing terms and conditions. The group of organs, cells, and hormones working together from the formation of female gamete, ova, to the parturition is the female reproductive system. Ovaries. The external female reproductive structures (the genital) has a twofold function: it works as a passage for the sperm to enter the body and also protects the internal genital organs from infectious organisms. Two hormones, follicle stimulating hormone (FSH) and. It provides a site for the development of the foetus. The competency of microbiology professionals is obtained through the theoretical knowledge gained in the class and the practical skills and applications that lead to the better understanding and interpretations the subject matter. Horn of uterus #6. In an adult female, the uterus weighs about 30-40 grams and is approximately 7.5cm long, 5cm wide with 2.5cm thick walls. The primary purpose of uterine tubes is to facilitate the transport of ovum from the ovary to the uterus. The intramural (interstitial) part that transverses the myometrium of the uterus. (2004) Anatomy and Physiology. The vagina is involved in sexual intercourse, childbirth and menstruation. In this section, learn more about the female reproductive tract, including the vulva, vagina, cervix, uterus, fallopian tubes, ovaries and the ligaments of the female reproductive tract. There are ~250 testicular lobules present. Anatomy of the female reproductive system. Both a sperm and an egg are needed for human reproduction. Perimetrium is the outermost layer of the uterus which is folded anteriorly to form the vesicouterine pouch. This system helps in both, fertilisation process as well as childbirth.

After menopause Effects of Aging on the Female Reproductive System Around menopause, changes in the female reproductive organs occur rapidly. It produces the female gametes called the eggs or ova. (e) Fimbriae Towards the ovarian end of the fallopian tube, finger-like projections emerge. The fallopian tubes have three layers: Physiology (Function) of the Female Reproductive System-Ovulation. It is made up of the vulva, the vagina, the cervix, the uterus, the fallopian tubes and the ovaries. The female reproductive organ that contains a shaft of erectile tissue that becomes engorged with blood during sexual stimulation is the. This causes the dominant follicle to release its egg from the ovary. Although the external genitalia is often referred to as the vagina, the vagina is present internally and is not part of the external genitalia. Progesterone hormone: Progesterone hormone regulates the inner lining (endometrium) of the uterus and also functions in the release of the egg during ovulation. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. The lowermost part of the uterus is known as the cervix, which is connected to the vagina. These fimbriae pick up the ovum when it is discharged from the ovary. The function of the external female reproductive structures (the genitals) is twofold: To enable sperm to enter the body and to protect the internal genital organs from infectious organisms. 2005 - 2022 WebMD LLC. Menopause commonly begins between the ages of 45 and 55. The area between the labia minora is called the vestibule and contains the openings of the urethra and vagina. Acromegaly. It is the process by which mature female gametes or ova develop from germ cells by the process of meiosis. The female lizard has much the same anatomy as that described for the snake. The corpus spongiosum penis corresponds to the female vestibular bulbs. Fertilization in humans takes place in the oviduct or fallopian tube at the ampullary isthmic junction. Fertilization combines the sperm of the male gamete with the ovum or the female gamete. It is fold of hair-covered skin. A collection of ligaments hold the ovaries in position and attach them to the uterus. The zygote is formed by merging of a sperm and an oocyte. ; Ampulla widest section of the uterine tubes.Fertilization usually occurs here. The external organs in the female reproductive system are collectively termed, vulva consisting of labia majora, labia minora, clitoris, vaginal orifice, vestibular gland, and hymen. The main parts of your vulva or external genitals are: The female reproductive system provides several functions. If the egg isnt fertilized, it dissolves in your uterus. However, the vagina stretches considerably during intercourse and childbirth. Thefemale reproductive systemis designed to carry out various functions. What are the parts of the female sexual anatomy? Between puberty and menopause, Lactobacillus acidophilus is found abundantly in the vagina. Sharma vs S.K. Mammary glands are balanced by the endocrine system and become functional due to the hormonal changes associated with parturition. Anteriorly, the folds join together in front of the pubis whereas anteriorly, they merge with the perineum. Generally, the lumen of the vagina is quite small and its walls touch one another. Due to the rhythmic contraction of the uterine muscles, the baby is pushed out from the mothers body through the vagina. These phases include: There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle. Healthline Media does not provide medical advice, diagnosis, or treatment. It has an anterior end that reaches close to the uncus of the cerebrum, a floor, and a roof.The roof of the inferior horn is formed mainly by the tapetum of the corpus callosum and the cauda of The vagina, uterus and fallopian tubes act as an accessory channel for the ovaries and the growing foetus. The ampulla is the longest part of the tubes with a length of 5cm. In males, the mammary gland is non-functional or vestigial or rudimentary. The reproductive system for females performs a number of critical functions for the species survival. Myometrium is the middle layer which is also the thickest layer in the uterine wall, which is composed of smooth muscles, connective tissues, blood vessels, and nerves. During this period, there are hormonal changes in the female. The cervix helps in allowing the discharge of menstrual fluid from the body. The female reproductive system is the body parts that help women or people assigned female at birth (AFAB): The female reproductive anatomy includes both external and internal parts. The common name "lamprey" is probably derived from Latin Your vulva is the collective name for all your external genitals. Then the zygote undergoes cleavage to form a solid ball of cells called morula. The infundibulum is a funnel-shaped structure that opens into the peritoneum of abdominal Ostia. Our website services, content, and products are for informational purposes only. Ovaries are female gonads or glands that exist in pairs in humans and each lie on the ovarian fossa present on the lateral wall of the pelvis. Their main function is to transmit the ovum to the uterus. Reproductive systems perform in both ways, forming gametes and fusing to form diploidzygotes. The channel is surrounded by a layer of mucous membrane folded into papillae. This is when your period begins. They are shorter and thinner than flagella. Ninth Edition. An ovary is the gonad of the female reproductive system which produces an ovum that develops into a zygote after fertilization. The permanent stoppage of menstruation at the age of about \(50\) years is called menopause. What is the overall function of the reproductive system? Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. Clitoris The female reproductive system performs the following functions: Oogenesis starts in the foetus prior to birth. Menstrual Cycle). The ovaries are the female gonads, and so are the site of gametogenesis. They include the mons pubis, the labia, the clitoris, the vaginal and urethral openings, and glands. They have no reproductive significance. Theovariesrelease these eggs. It has an upside-down pear shape and is about 3 inches long by 2 inches wide by 1 inch deep. The epithelial cells also secrete glycogen, which resident bacteria break down to produce ATP and lactic acid. Last reviewed by a Cleveland Clinic medical professional on 11/28/2022.

Altogether, the uterus has three sections as well as three layers: As well as having three aspects or parts, the uterus also has three layers. The wide distal infundibulum flares out with slender, finger-like projections called fimbriae. Into this groove sperm and spermatic fluid will drop from the cloaca, and the hemipene will guide this into the female lizards cloaca. The oviducts or fallopian tubes, uterus, and vagina are the accessory reproductive organs of the female reproductive system. The vagina is present obliquely upwards bent at an angle of 45 with the bladder in front and rectum and anus behind. Also, it expands in size during pregnancy to meet the needs of the growing baby. This causes the dominant follicle to release its egg from the ovary. Morula then transforms into a hollow structure called the blastocyst. Further, the lateral ends of the fallopian tubes are open and comprise projections called fimbriae that drape over the ovary. Frimbriae are fine extensions from a cell. The average menstrual cycle takes about 28 days and occurs in phases: the follicular phase, the ovulatory phase (ovulation), and the luteal phase.

Function of uterus in female reproductive system. It is also provided with a large number of sebaceous glands. The primary organs of reproduction in the female are the ovaries. The mature follicles are called the Graafian follicle. An ovary is surrounded by a capsule which encloses an outer cortex and an inner medulla. The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced by the. Each primary ovarian follicle contains an oocyte, a potential ovum or egg cell. These signs are the bodys reactions to the hormones generated during the fertilization process. Structure: The ovaries are the primary reproductive organs present in the female reproductive system. There are two kinds of sex cells sperm and eggs.
