Anatomy of the Female Reproductive System
The reproductive role of the female is far more complex than that of a male. Not only must she produce gametes, but her body must prepare to nurture a developing embryo for a period of approximately nine months. Ovaries, the female gonads, are the primary reproductive organs of a female, and like the male testes, ovaries serve a dual purpose: They produce the female gametes (ova) and sex hormones, the estrogens * and progesterone (pro-ges′tĕ-rōn). The accessory ducts (uterine tubes, uterus, and vagina) transport or otherwise serve the needs of the reproductive cells and a developing fetus. As illustrated in Figure 27.11, the ovaries and duct system, collectively known as the internal

Each uterine tube is about 10 cm (4 inches) long and extends medially from the region of an ovary to empty into the superolateral region of the uterus via a constricted region called the isthmus (is′mus). The distal end of each uterine tube expands as it curves around the ovary, forming the ampulla; fertilization usually occurs in this region. The ampulla ends in the infundibulum (in″fun-dib′u-lum), an open, funnel-shaped structure bearing ciliated, fingerlike projections called fimbriae (fim′bre-e; “fringe”) that drape over the ovary. Unlike the male duct system, which is continuous with the tubules of the testes, the uterine tubes have little or no actual contact with the ovaries. An ovulated oocyte is cast into the peritoneal cavity, and many oocytes are lost there. However, the uterine tube performs complex movements to capture oocytes–it bends to drape over the ovary while the fimbriae stiffen and sweep the ovarian surface. The beating cilia on the fimbriae then create currents in the peritoneal fluid that tend to carry an oocyte into the uterine tube, where it begins its journey toward the uterus.
The uterine tube contains sheets of smooth muscle, and its thick, highly folded mucosa contains both ciliated and nonciliated cells. The oocyte is carried toward the uterus by a combination of muscular peristalsis and the beating of the cilia. Nonciliated cells of the mucosa have dense
The female reproductive system contains two ovaries. The ovaries nourish the eggs as they mature and are ready for fertilization. An egg will come to maturity approximately every 28 days. When the ovum has matured, the ovary releases it in a process called ovulation. After ovulation the ovum moves into the fallopian tube adjacent to the ovary.
tissue to form in the fallopian tubes. If the tube is only partially scarred, the fertilized egg cannot
Testes: The function of the testes (following puberty) is to produce spermatozoa and androgens, mainly testosterone. The testes produce sperm; about 300 million are released with each ejaculation.
The ovaries are a pair of organs in the female reproductive system located on the lateral walls of the female pelvic cavity. Martini, Nath & Bartholomew,(2014)
The reproductive system is a system of sex organs within an organism which work together for sexual reproduction. The development of the reproductive system is controlled by the pituitary
Firstly, the female reproductive system consists of the ovaries, uterus, breasts, vagina, fallopian tube, vulva and mammary glands. These seven organs
What is the role of the vasa recta? Blood capillary which collects the filtered blood capillary which collects the filtered blood from afferent arterriole
The Female Reproductive System parts are gametes, which is a mature haploid male or female germ cell that is able to unite with another of the opposite sex in several reproductions to form a zygote. Egg is a person possessing a specified quantity. Ovum is a mature female reproductive cell especially of a human or other animal that van divide to give rise to an embryo usually only after fertilization by a male cell. Vaginal is a muscular tube leading from the external genitals to the cervix of the uterus in women and most female mammals. Labia is the inner and outer folds of the vulva, at either side of the vagina. Clitoris is a small sensitive and erectile part of the female genitals at the anterior end of the vulva. Urethra is a duct by
The penis is the male organ through which sperm cells are transferred from the male to the female. The penis contains three columns of erectile tissue. Engorgement of this erectile tissue with blood causes the penis to enlarge and become firm this process is called erection. Two of the erectile columns form the dorsum and sides of the penis and are called the corpora cavernosa. The third column, the corpus spongiosum, forms the ventral portion of the penis. It expands to form a cap over the distal end of the penis. The spongy urethra passes through the corpus spongiosum, penetrates the glans penis, and opens as the external urethral orifice. At the base of
The hormones that the ovaries produce are estrogen and progesterone, which are mandatory for healthy reproduction. Also the hormone androgen plays a role in the regulation of normal ovarian function. Androgen is the male hormone but it is very important in a woman’s reproductive health. Androgen becomes a problem in the woman when too much is produced and stops ovulation. A woman is born with all the eggs she will ever have for the rest of her life. At the time of ovulation, the egg develops and is called a follicle. In those follicles, a small amount of fluid is starting to gather. If the egg goes into full maturity and ovulation happens, the follicle will become enlarged. Each month during the normal ovarian cycle some follicles will begin to develop but never make it to ovulation.
The proximal convoluted tubule measures approximately 14 mm long and 60 μm in diameter. Simple cuboidal epithelium makes up its wall. The cells rest on a basement membrane, which forms the outer surface of the tubule. The loops of Henle are continuations of the proximal convoluted tubules. Each loop has two limbs: the descending limb and the ascending limb. The first part of the descending limb is similar in structure to the proximal convoluted tubules. The loops of Henle that extend into the medulla become very thin near the end of the loop. The lumen in the thin part narrows, and an abrupt transition
http://kidshealth.org/parent/interactive/frs_it.html In this interactive diagram/demonstration we have pictured the vagina, uterus, fallopian tubes, and the ovaries. When you scroll over a particular part of the picture it will give you the name, what it is, and the function of that part. For instance if you scrolled over the Fallopian Tubes it will tell you that it is a thin soft tube that connects the Uterus to the Ovaries. During ovulation the ovaries will release an egg/s and they will travel through the fallopian tube to the uterus. Essentially it’s the road way. I find this valuable because you can tell someone something about their body all day long but it’s nothing like seeing what it is and how it works for you to
The ovary, or female gonad, is one of a pair of reproductive glands in women.
Do you know how you were born? Do you know how you came to be? The reproductive system is the system that made that all possible. Without the reproductive system you wouldn’t have been born. In order to produce offspring, the male and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg.
