Where Are Female Eggs Stored Where Does a Baby Grow During Pregnancy

How does the female reproductive system work?

The female person reproductive organisation provides several functions. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are so transported to the fallopian tube where fertilization past a sperm may occur. The fertilized egg so moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive wheel. Once in the uterus, the fertilized egg can implant into thickened uterine lining and continue to develop. If implantation does not take place, the uterine lining is shed as menstrual flow. In improver, the female person reproductive system produces female sex hormones that maintain the reproductive wheel.

During menopause, the female reproductive arrangement gradually stops making the female hormones necessary for the reproductive bicycle to work. At this point, menstrual cycles can become irregular and eventually cease. One year afterward menstrual cycles stop, the woman is considered to be menopausal.

What parts brand-up the female anatomy?

The female person reproductive anatomy includes both external and internal structures.

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

The master external structures of the female reproductive system include:

• Labia majora: The labia majora ("large lips") enclose and protect the other external reproductive organs. During puberty, pilus growth occurs on the peel of the labia majora, which also incorporate sweat and oil-secreting glands.
• Labia minora: The labia minora ("modest lips") can accept a variety of sizes and shapes. They lie just inside the labia majora, and surround the openings to the vagina (the canal that joins the lower part of the uterus to the outside of the body) and urethra (the tube that carries urine from the bladder to the outside of the body). This pare is very frail and tin go easily irritated and swollen.
• Bartholin'south 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-scale, sensitive protrusion that is comparable to the penis in males. The clitoris is covered by a fold of skin, called 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 erect.

The internal reproductive organs include:

• Vagina: The vagina is a culvert that joins the cervix (the lower office of uterus) to the outside of the body. It also is known as the birth canal.
• Uterus (womb): The uterus is a hollow, pear-shaped organ that is the home to a developing fetus. The uterus is divided into two parts: the cervix, which is the lower part that opens into the vagina, and the chief body of the uterus, called the corpus. The corpus can easily aggrandize to hold a developing babe. A culvert through the cervix allows sperm to enter and menstrual blood to go out.
• Ovaries: The ovaries are small, 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 office 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 commonly occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants to the uterine lining.

What happens during the menstrual bicycle?

Females of reproductive historic period (starting time anywhere from 11 to 16 years of age) experience cycles of hormonal activity that echo at about ane-month intervals. Menstru means "monthly" – leading to the term menstrual bike. With every cycle, a woman'southward body prepares for a potential pregnancy, whether or non that is the woman's intention. The term menstruation refers to the periodic shedding of the uterine lining. Many women call the days that they observe vaginal haemorrhage their "menses," "menstrual" or cycle.

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

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

At that place are four 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 stage

This stage starts on the commencement day of your period. During the follicular phase of the menstrual wheel, the post-obit events occur:

• Two hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH) are released from the brain and travel in the blood to the ovaries.
• The hormones stimulate the growth of about 15 to 20 eggs in the ovaries, each in its own "beat out," called a follicle.
• These hormones (FSH and LH) also trigger an increase in the production of the female hormone estrogen.
• As estrogen levels rise, like a switch, information technology turns off the production of follicle-stimulating hormone. This careful residuum of hormones allows the torso to limit the number of follicles that will fix eggs to exist released.
• As the follicular phase progresses, 1 follicle in one ovary becomes dominant and continues to mature. This dominant follicle suppresses all of the other follicles in the group. As a result, they stop growing and die. The dominant follicle continues to produce estrogen.

Ovulatory stage

The ovulatory phase (ovulation) usually starts about 14 days after the follicular phase started, simply this can vary. The ovulatory phase falls between the follicular stage and luteal phase. Almost women will have a menstrual period 10 to 16 days later on ovulation. During this phase, the following events occur:

• The rising in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced past the brain.
• This causes the ascendant follicle to release its egg from the ovary.
• As the egg is released (a procedure called ovulation) it is captured past finger-similar projections on the cease of the fallopian tubes (fimbriae). The fimbriae sweep the egg into the tube.
• For one to five days prior to ovulation, many women will notice an increase in egg white cervical mucus. This mucus is the vaginal discharge that helps to capture and nourish sperm on its way to meet the egg for fertilization.

Luteal phase

The luteal phase begins right after ovulation and involves the following 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 human'south sperm has fertilized the egg (a process called formulation), the fertilized egg (embryo) will travel through the fallopian tube to implant in the uterus. The woman is now considered pregnant.
• If the egg is not fertilized, it passes through the uterus. Non needed to support a pregnancy, the lining of the uterus breaks downwards and sheds, and the next menstrual flow begins.

How many eggs does a woman have?

During fetal life, there are about vi meg to 7 million eggs. From this time, no new eggs are produced. At birth, there are approximately one 1000000 eggs; and by the time of puberty, but about 300,000 remain. Of these, simply 300 to 400 volition be ovulated during a woman'south reproductive lifetime. Fertility tin drib every bit a adult female ages due to decreasing number and quality of the remaining eggs.
