What Are the Two Tubes That Carry the Ova From the Ovaries to the Uterus?

How does the female reproductive system work?

The female reproductive system provides several functions. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then 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. One time 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 menses. In improver, the female person reproductive system produces female person sex hormones that maintain the reproductive cycle.

During menopause, the female person reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work. At this point, menstrual cycles can go irregular and eventually end. One year after menstrual cycles end, the adult female is considered to be menopausal.

What parts make-upwards the female beefcake?

The female reproductive anatomy 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 main external structures of the female person reproductive system 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 as well comprise sweat and oil-secreting glands.
• Labia minora: The labia minora ("small lips") can have a variety of sizes and shapes. They lie but inside the labia majora, and surroundings the openings to the vagina (the canal that joins the lower function of the uterus to the outside of the body) and urethra (the tube that carries urine from the bladder to the exterior of the body). This skin is very delicate and tin can get hands irritated and swollen.
• Bartholin's glands: These glands are located next to the vaginal opening on each side and produce a fluid (fungus) secretion.
• Clitoris: The two labia minora encounter at the clitoris, a small, sensitive protrusion that is comparable to the penis in males. The clitoris is covered by a fold of peel, called the prepuce, which is similar to the foreskin at the end of the penis. Similar the penis, the clitoris is very sensitive to stimulation and can get erect.

The internal reproductive organs include:

• Vagina: The vagina is a canal that joins the cervix (the lower part of uterus) to the exterior of the body. It besides is known every bit 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 neck, which is the lower office that opens into the vagina, and the main trunk of the uterus, called the corpus. The corpus can easily expand to hold a developing infant. A canal through the neck allows sperm to enter and menstrual blood to exit.
• 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 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 cycle?

Females of reproductive age (showtime anywhere from xi to 16 years of historic period) feel cycles of hormonal activeness that repeat at about one-month intervals. Menstru ways "monthly" – leading to the term menstrual cycle. With every cycle, a woman's body prepares for a potential pregnancy, whether or not that is the woman'south intention. The term menstruation refers to the periodic shedding of the uterine lining. Many women call the days that they observe vaginal bleeding their "period," "menstrual" or cycle.

The average menstrual wheel takes virtually 28 days and occurs in phases. These phases include:

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

In that location are four major hormones (chemicals that stimulate or regulate the activeness of cells or organs) involved in the menstrual bike. These hormones include:

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

Follicular phase

This stage starts on the first day of your period. During the follicular phase of the menstrual cycle, 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 ain "shell," 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, it turns off the production of follicle-stimulating hormone. This careful balance of hormones allows the trunk to limit the number of follicles that will prepare eggs to exist released.
• Every bit the follicular phase progresses, one follicle in one ovary becomes ascendant and continues to mature. This dominant follicle suppresses all of the other follicles in the group. As a event, they terminate 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, just this can vary. The ovulatory phase falls between the follicular phase and luteal phase. Most women will have a menstrual period 10 to sixteen days afterward 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.
• As the egg is released (a procedure called ovulation) it 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 5 days prior to ovulation, many women will observe an increase in egg white cervical mucus. This mucus is the vaginal discharge that helps to capture and nourish sperm on its mode to come across the egg for fertilization.

Luteal phase

The luteal phase begins right afterwards ovulation and involves the following processes:

• One time it releases its egg, the empty ovarian follicle develops into a new structure 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 conception), the fertilized egg (embryo) will travel through the fallopian tube to implant in the uterus. The woman is at present considered significant.
• If the egg is not fertilized, it passes through the uterus. Not needed to support a pregnancy, the lining of the uterus breaks downwards and sheds, and the next menstrual period begins.

How many eggs does a woman accept?

During fetal life, there are virtually six meg to 7 meg eggs. From this fourth dimension, no new eggs are produced. At birth, in that location are approximately 1 1000000 eggs; and by the fourth dimension of puberty, only almost 300,000 remain. Of these, but 300 to 400 volition exist ovulated during a woman'due south reproductive lifetime. Fertility can drop equally a adult female ages due to decreasing number and quality of the remaining eggs.
