Fertilized Eggs Mature Into a Baby Within the Cervix

How does the female reproductive system piece of work?

The female reproductive organisation provides several functions. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are and so transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle. Once in the uterus, the fertilized egg can implant into thickened uterine lining and go along to develop. If implantation does not accept identify, the uterine lining is shed equally menstrual flow. In add-on, the female reproductive system produces female person sex hormones that maintain the reproductive bicycle.

During menopause, the female reproductive arrangement gradually stops making the female hormones necessary for the reproductive cycle to work. At this point, menstrual cycles can become irregular and eventually end. One yr after menstrual cycles finish, the woman is considered to be menopausal.

What parts make-up the female person anatomy?

The female reproductive beefcake includes both external and internal structures.

The function of the external female reproductive structures (the genital) is twofold: To enable sperm to enter the body and to protect the internal genital organs from infectious organisms.

The principal external structures of the female reproductive organization include:

• Labia majora: The labia majora ("large lips") enclose and protect the other external reproductive organs. During puberty, hair growth occurs on the skin of the labia majora, which too contain sweat and oil-secreting glands.
• Labia minora: The labia minora ("small lips") tin have a diversity of sizes and shapes. They prevarication merely inside the labia majora, and environment the openings to the vagina (the canal that joins the lower part of the uterus to the outside of the torso) and urethra (the tube that carries urine from the bladder to the exterior of the trunk). This skin is very delicate and tin can get easily irritated and bloated.
• Bartholin's glands: These glands are located next to the vaginal opening on each side and produce a fluid (mucus) secretion.
• Clitoris: The two labia minora meet at the clitoris, a small, sensitive protrusion that is comparable to the penis in males. The clitoris is covered by a fold of peel, chosen the prepuce, which is similar to the foreskin at the end of the penis. Like the penis, the clitoris is very sensitive to stimulation and can become cock.

The internal reproductive organs include:

• Vagina: The vagina is a canal that joins the cervix (the lower function of uterus) to the outside of the body. It also is known as the nascence canal.
• Uterus (womb): The uterus is a hollow, pear-shaped organ that is the domicile to a developing fetus. The uterus is divided into 2 parts: the cervix, which is the lower part that opens into the vagina, and the main trunk of the uterus, chosen the corpus. The corpus can easily aggrandize to concur a developing baby. A canal through the cervix allows sperm to enter and menstrual blood to exit.
• Ovaries: The ovaries are modest, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs and hormones.
• Fallopian tubes: These are narrow tubes that are attached to the upper part of the uterus and serve as pathways for the ova (egg cells) to travel from the ovaries to the uterus. Fertilization of an egg by a sperm normally occurs in the fallopian tubes. The fertilized egg and then moves to the uterus, where it implants to the uterine lining.

What happens during the menstrual wheel?

Females of reproductive age (beginning anywhere from eleven to 16 years of age) experience cycles of hormonal action that repeat at about one-calendar month intervals. Menstru means "monthly" – leading to the term menstrual bicycle. With every bike, a woman'south torso prepares for a potential pregnancy, whether or not that is the adult female's intention. The term catamenia refers to the periodic shedding of the uterine lining. Many women call the days that they discover vaginal bleeding their "period," "menstrual" or cycle.

The average menstrual cycle takes about 28 days and occurs in phases. These phases include:

• The follicular stage (development of the egg)
• The ovulatory stage (release of the egg)
• The luteal phase (hormone levels decrease if the egg does not implant)

There are 4 major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle. These hormones include:

• Follicle-stimulating hormone
• Luteinizing hormone
• Estrogen
• Progesterone

Follicular phase

This phase starts on the first 24-hour interval of your period. During the follicular stage of the menstrual cycle, the following events occur:

• Two hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH) are released from the encephalon and travel in the blood to the ovaries.
• The hormones stimulate the growth of virtually 15 to 20 eggs in the ovaries, each in its own "shell," chosen a follicle.
• These hormones (FSH and LH) also trigger an increase in the production of the female person hormone estrogen.
• As estrogen levels rise, like a switch, information technology turns off the production of follicle-stimulating hormone. This careful remainder of hormones allows the torso to limit the number of follicles that will prepare eggs to exist released.
• As the follicular stage progresses, 1 follicle in 1 ovary becomes ascendant and continues to mature. This dominant follicle suppresses all of the other follicles in the group. Every bit a result, they terminate growing and die. The ascendant follicle continues to produce estrogen.

Ovulatory phase

The ovulatory phase (ovulation) commonly starts nearly 14 days after the follicular phase started, but this can vary. The ovulatory phase falls between the follicular phase and luteal phase. About women volition take a menstrual period 10 to sixteen days after ovulation. During this phase, the following events occur:

• The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced by the brain.
• This causes the dominant follicle to release its egg from the ovary.
• Equally the egg is released (a process called ovulation) information technology is captured by finger-like projections on the end of the fallopian tubes (fimbriae). The fimbriae sweep the egg into the tube.
• For one to five days prior to ovulation, many women will detect an increase in egg white cervical fungus. This mucus is the vaginal belch that helps to capture and nourish sperm on its style to run across the egg for fertilization.

Luteal stage

The luteal phase begins right afterwards ovulation and involves the post-obit processes:

• One time it releases its egg, the empty ovarian follicle develops into a new construction called the corpus luteum.
• The corpus luteum secretes the hormones estrogen and progesterone. Progesterone prepares the uterus for a fertilized egg to implant.
• If intercourse has taken place and a homo's sperm has fertilized the egg (a process called conception), the fertilized egg (embryo) volition travel through the fallopian tube to implant in the uterus. The woman is at present considered pregnant.
• If the egg is not fertilized, it passes through the uterus. Not needed to support a pregnancy, the lining of the uterus breaks down and sheds, and the next menstrual period begins.

How many eggs does a woman have?

During fetal life, there are about half-dozen million to 7 one thousand thousand eggs. From this fourth dimension, no new eggs are produced. At birth, there are approximately ane 1000000 eggs; and by the time of puberty, only well-nigh 300,000 remain. Of these, just 300 to 400 volition be ovulated during a woman'south reproductive lifetime. Fertility can drop equally a woman ages due to decreasing number and quality of the remaining eggs.
