what happens to eggs when have a tube

How does the female reproductive system piece of 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 bike. 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 addition, the female reproductive arrangement produces female sex hormones that maintain the reproductive wheel.

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

What parts make-upward the female beefcake?

The female reproductive anatomy includes both external and internal structures.

The part 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 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 likewise contain sweat and oil-secreting glands.
• Labia minora: The labia minora ("small lips") can accept a variety of sizes and shapes. They prevarication only inside the labia majora, and surround the openings to the vagina (the canal that joins the lower part of the uterus to the exterior of the torso) and urethra (the tube that carries urine from the bladder to the outside of the body). This skin is very fragile and can become hands irritated and swollen.
• Bartholin's glands: These glands are located adjacent to the vaginal opening on each side and produce a fluid (mucus) secretion.
• Clitoris: The ii labia minora come across at the clitoris, a small, sensitive protrusion that is comparable to the penis in males. The clitoris is covered by a fold of skin, chosen the prepuce, which is like to the foreskin at the finish 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 office of uterus) to the outside of the torso. Information technology likewise is known equally the nativity 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 main body of the uterus, called the corpus. The corpus can hands expand to hold a developing baby. A canal through the neck 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 role of the uterus and serve as pathways for the ova (egg cells) to travel from the ovaries to the uterus. Fertilization of an egg past a sperm unremarkably 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 age (first anywhere from 11 to 16 years of age) feel cycles of hormonal action that echo at about i-month intervals. Menstru means "monthly" – leading to the term menstrual cycle. With every cycle, a woman's torso prepares for a potential pregnancy, whether or not that is the woman'due south intention. The term catamenia refers to the periodic shedding of the uterine lining. Many women call the days that they notice vaginal bleeding their "period," "menstrual" or bicycle.

The boilerplate 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 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 first twenty-four hour period of your flow. During the follicular phase of the menstrual cycle, the following events occur:

• Ii hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH) are released from the brain and travel in the claret to the ovaries.
• The hormones stimulate the growth of almost fifteen to twenty eggs in the ovaries, each in its own "shell," called a follicle.
• These hormones (FSH and LH) also trigger an increment in the product of the female person hormone estrogen.
• As estrogen levels rise, like a switch, it turns off the production of follicle-stimulating hormone. This careful residual of hormones allows the body to limit the number of follicles that will prepare eggs to be released.
• Equally the follicular stage progresses, one follicle in one ovary becomes dominant and continues to mature. This dominant follicle suppresses all of the other follicles in the grouping. As a result, they stop growing and die. The ascendant follicle continues to produce estrogen.

Ovulatory stage

The ovulatory phase (ovulation) commonly starts near 14 days after the follicular stage started, merely this can vary. The ovulatory phase falls between the follicular phase and luteal stage. Most women will take a menstrual period 10 to xvi days afterwards ovulation. During this phase, the post-obit 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-similar 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 notice an increase in egg white cervical mucus. This mucus is the vaginal belch that helps to capture and nourish sperm on its way to meet the egg for fertilization.

Luteal phase

The luteal stage begins right after ovulation and involves the following processes:

• One time information technology 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 identify and a man'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 at present considered pregnant.
• If the egg is not fertilized, information technology passes through the uterus. Non needed to back up a pregnancy, the lining of the uterus breaks downward and sheds, and the next menstrual menstruum begins.

How many eggs does a woman accept?

During fetal life, there are about vi one thousand thousand to seven million eggs. From this time, no new eggs are produced. At nativity, there are approximately ane million eggs; and by the fourth dimension of puberty, simply about 300,000 remain. Of these, merely 300 to 400 will be ovulated during a adult female's reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.
