Female Reproductive System Anatomy
Ovaries
The ovaries are a pair of small glands about the size and shape of almonds, located on the left and right sides of the pelvic body cavity lateral to the superior portion of the uterus. Ovaries produce female sex hormones such as estrogen and progesterone as well as ova (commonly called "eggs"), the female gametes. Ova are produced from oocyte cells that slowly develop throughout a woman’s early life and reach maturity after puberty. Each month during ovulation, a mature ovum is released. The ovum travels from the ovary to the fallopian tube, where it may be fertilized before reaching the uterus.
Fallopian Tubes
The fallopian tubes are a pair of muscular tubes that extend from the left and right superior corners of the uterus to the edge of the ovaries. The fallopian tubes end in a funnel-shaped structure called the infundibulum, which is

    The ovaries contain hundreds of undeveloped female sex cells called egg cells; women are born with these cells in their bodies. The ovaries are connected to the uterus by a tube called a fallopian tube. Each month an egg is released from an ovary it then develops and becomes mature. The uterus is where a baby develops until birth. At the the lower end of the uterus there is a ring of muscle called the cervix which keeps the baby in place whilst a woman is pregnant.…

    Each month inside your ovaries, a group of eggs starts to grow. Eventually one of the eggs erupts from the follicle and this is known as ovulation. It usually happens about two weeks before your next period. A hormone is released that helps thicken the lining of your uterus, getting it ready for the egg. After the egg is released, it moves into the fallopian tube. When a sperm does make its way into the Fallopian tube and burrow into the egg, it fertilises the egg. The egg changes so that no other sperm can get in. The egg stays in the Fallopian tube for about three to four days, but within 24 hours of being fertilised it starts dividing very fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. The developing collection of cells is now called an embryo and is attached to the wall of the uterus by a placenta. Chemicals are released to prevent the women having another menstrual period.…

    The fallopian tubes are the structures that carry a mature egg from the ovaries to the uterus. These tubes, which are about 4 in (10 cm) in length and 0.2 (0.5 cm) in diameter, are located on the upper outer sides of the uterus, and open into the uterus through small channels. And 'inside of the fallopian tubes that fertilization, the union of an egg and a sperm, takes place.…

    17. The female gonads, or ovaries, under the influence of FSH, develop mature folliclescontaining an oocyte. The follicle cells secrete the hormone estrogen that causes the lining of the uterus to build up. A LH spike causes ovulation, and the surrounding follicle tissue develops into a corpus luteum that now also makes progesterone. Under the influence of progesterone, the lining of the uterus develops secretions to sustain an early embryo. If there is no production ofGnRH by the early embryo, the corpus luteum shrinks and the lining of the uterus sloughs in the process called…

    The aim of the female reproductive system is to produce mature oocytes which match with the male spermatocyte to create offspring. Fertilisation most commonly occurs in the fallopian tubes, though this can also occur later in a female’s menstrual cycle if the egg has already moved down into the uterus, though there is a higher chance of miscarriage as the lining of the womb may continue to shed. The external female reproduction features have two functions; to allow insemination and to also protect against infection and injury. These structures include; the labia majora, which contains glands that produce sweat, the labia minora which surrounds the opening of the vagina and urethra, bartholin's glands which are just behind the vaginal…

    The male reproductive system includes the Testes and the Penis, the Testes is where sperm are produced, and the major internal organs of the female reproductive system include the Vagina and the Uterus, in which act as a receptor for the sperm. The Ovaries produce the female's ova l, and the Vagina is attached to the Uterus through the cervix, while the fallopian tubes connect to the Uterus to the Ovaries. Fertilization occurs if a sperm enters the fallopian tube and burrows into the egg, when the fetus produces I mature enough to survive outside I the womb the cervix dilates and contradictions of the Uterus propel it through the birth canal.…

    In women the external organs in the reproductive system are the clitoris, labia minora and Bartholin's glands. The internal organs are the vagina and the uterus. The uterus acts as the replacement for semen. Also, the ovaries produce the female’s ova (eggs). The vagina is attached to the uterus through the cervix, while the fallopian tubes connect the uterus to the ovaries. In response…

    The reproductive system is questionably the body system that is the most important influence on life as we know it. It is the w ay in which we procreate and ensure our existence as a species. However, the penis is only one part of the male reproductive system, which constitutes of a series responsible for generating, storing, and transporting the genetic material contained in the sperm cells. The main organs include: testicles (or testes), the epididymides, the vas deferens, the ejaculatory duct, the urethra, and the penis. Others are the scrotum, urogenital opening, and the prostate gland.…

    The follicular phase starts on the first day of menstruation and ends with ovulation. The pituitary gland produces a hormone that stimulates the egg cells in the ovaries to grow. One of these egg cells begins to mature in a sac-like-structure called follicle. It takes 13 days for the egg cell to reach maturity. While the egg cell matures, its follicle produces a hormone that stimulates the uterus to develop a lining of blood vessels and soft tissue called endometrial.…

    This is the name for the sex gland that is similar in function to the male testicle. They are two in number and are located on either side of the uterus (womb). Each ovary is coverd by a tough protective capsule and contains many follicles. A follicle-sound is an egg cell sourounded by one or more layers of follicle cells. It is estimated that about 400,000 eggs (ovum) are stored in eachovary at birth. However, only one egg becomes ripe each month, once puberty begins, and departs from the ovary and travels into the fallopian tubes (oviduct). They also manufacture the female hormones estrogen and progesterone which is instrumental in the onset of the menstrual cycle.…

    Sandy responded, “That’s amazing, the cervix lies amongst the vagina and the lower end of the uterus. The cervix produces secretion that adds to the vagina's chemical balance. It has a small opening about the size of a straw that swells allowing sperm to pass through from the vagina to the uterus as well as allowing a baby to move from the uterus to the vagina during child birth" (Rathus, Nevid, & Fichner-Rathus, 2005).…

    Reproductive System

    The female reproductive tract is composed of paired right and left ovaries, oviducts, and uterine horns. It contains only a single cervix, vagina and vulva (external genitalia). Collectively, these structures are supported by the broad ligament and hang loosely suspended below the rectum in the both pelvic canal and lower abdomen. The broad ligament is made of tough connective tissue, attaching near the point of the spine, and running continuously with the inner most layer of the abdominal cavity. Many of the blood vessels and nerves travel through this large piece tissue in order to supply the reproductive tract with blood, hormones and neural stimuli. In prepubertal gilts, the ligament is short, paper thin, and almost transparent. However, in late pregnancy it becomes very long as it stretches and thickens in order to support the increasing weight of the pregnant reproductive tract.…
