How walk the mrs reproductive mechanism work?

The mrs reproductive system offers several functions. The ovaries create the egg cells, referred to as the ova or oocytes. The oocytes are then transported come the fallopian tube wherein fertilization by a sperm might occur. The fertilized egg then moves to the uterus, wherein the uterine lining has actually thickened in solution to the typical hormones the the reproductive cycle. Once in the uterus, the fertilized egg deserve to implant right into thickened uterine lining and also continue to develop. If implantation does no take place, the uterine lining is burned as menstrual flow. In addition, the mrs reproductive mechanism produces female sex hormone that keep the reproductive cycle.

During menopause, the female reproductive system slowly stops make the mrs hormones crucial for the reproductive cycle to work. At this point, expression cycles can come to be irregular and eventually stop. One year after menstrual cycles stop, the woman is thought about to be menopausal.

What parts make-up the mrs

The female reproductive has both external and also internal structures.

The function of the outside female reproductive frameworks (the genital) is twofold: To permit sperm to enter the body and to defend the inner genital guts from contagious organisms.

The main external structures of the woman reproductive device include:

Labia majora: The labia majora (“large lips”) enclose and also protect the other exterior reproductive organs. Throughout puberty, hair growth occurs top top the skin the the labia majora, which additionally contain sweat and oil-secreting glands.Labia minora: The labia minora (“small lips”) have the right to have a range of sizes and shapes. They lie simply 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 body) and also urethra (the tube that carries urine from the bladder to the outside of the body). This skin is really delicate and also can become easily irritated and also swollen.Bartholin’s glands: this glands are situated next to the vaginal opening on every side and produce a liquid (mucus) secretion.Clitoris: The two labia minora satisfy at the clitoris, a small, sensitive protrusion that is equivalent to the dick in males. The clitoris is covered by a fold of skin, called the prepuce, i m sorry is comparable to the foreskin in ~ the end of the penis. Like the penis, the clitoris is really sensitive to stimulation and also can end up being erect.


The internal reproductive guts include:

Vagina: The vagina is a canal that joins the cervix (the lower part 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 body organ that is the house to a developing fetus. The uterus is split into 2 parts: the cervix, which is the lower part that opens into the vagina, and the key body of the uterus, dubbed the corpus. The body can conveniently expand to hold a occurring baby. A canal v the cervix permits sperm to enter and menstrual blood to exit.Ovaries: The ovaries space small, oval-shaped glands the are situated on either next of the uterus. The ovaries create eggs and also hormones.Fallopian tubes: These space narrow pipe that space attached come the upper component of the uterus and also serve together pathways because that the ova (egg cells) to travel from the ovaries come the uterus. Fertilization of an egg by a sperm usually occurs in the fallopian tubes. The fertilized egg then moves come the uterus, where it implants to the uterine lining.


What happens throughout the expression cycle?

Females of reproductive period (beginning anywhere from 11 come 16 year of age) experience cycles that hormonal task that repeat at around one-month intervals. Menstru way "monthly” – leading to the term menstrual cycle. Through every cycle, a woman’s human body prepares because that a potential pregnancy, even if it is or no that is the woman’s intention. The hatchet menstruation refers to the routine shedding the the uterine lining. Countless women speak to the days the they notification vaginal bleeding their “period,” “menstrual” or cycle.

The typical menstrual bike takes about 28 days and also occurs in phases. This phases include:

The follicular step (development of the egg)The ovulatory phase (release that the egg)The luteal phase (hormone level decrease if the egg does not implant)


There room four significant hormones (chemicals that stimulate or control the activity of cells or organs) connected in the menstrual cycle. These hormones include:

Follicle-stimulating hormoneLuteinizing hormoneEstrogenProgesterone

Follicular phase

This step starts top top the an initial day of your period. During the follicular phase of the expression cycle, the following occasions occur:

Two hormones, follicle stimulating hormone (FSH) and also luteinizing hormone (LH) space released indigenous the brain and travel in the blood come the ovaries.The hormone stimulate the expansion of about 15 to 20 eggs in the ovaries, each in its very own "shell," referred to as a follicle.These hormone (FSH and also LH) likewise trigger an increase in the production of the female hormone estrogen.As estrogen levels rise, favor a switch, it transforms off the manufacturing of follicle-stimulating hormone. This cautious balance of hormones allows the body to limit the number of follicles that will certainly prepare eggs to it is in released.As the follicular step progresses, one follicle in one ovary becomes dominant and continues to mature. This leading follicle suppresses all of the various other follicles in the group. Together a result, they protect against growing and die. The leading follicle proceeds to produce estrogen.

Ovulatory phase

The ovulatory phase (ovulation) generally starts about 14 work after the follicular step started, yet this deserve to vary. The ovulatory step falls in between the follicular phase and luteal phase. Most women will have actually a menstrual period 10 come 16 days after ovulation. During this phase, the following events occur:

The climb in estrogen native the leading follicle root cause a rise in the lot of luteinizing hormone the is produced by the brain.This causes the leading follicle to relax its egg native the ovary.As the egg is released (a procedure called ovulation) it is captured by finger-like projections top top the end of the fallopian tubes (fimbriae). The fimbriae sweep the egg right into the tube.For one to five days prior to ovulation, numerous women will notification an boost in egg white cervical mucus. This mucus is the vaginal discharge that helps come capture and nourish sperm on its way to satisfy the egg for fertilization.

Luteal phase

The luteal phase starts right ~ ovulation and involves the following processes:

Once the releases that egg, the north ovarian follicle establishes into a brand-new structure dubbed the corpus luteum.The body luteum secretes the hormones estrogen and also progesterone. Progesterone prepares the uterus for a fertilized egg come implant.If intercourse has taken place and also a man's sperm has actually fertilized the egg (a procedure called conception), the fertilized egg (embryo) will certainly travel through the fallopian tube to implant in the uterus. The woman is now taken into consideration pregnant.If the egg is no fertilized, that passes v the uterus. Not required to assistance a pregnancy, the lining that the uterus division down and sheds, and also the following menstrual duration begins.

How countless eggs go a woman have?

During fetal life, over there are around 6 million to 7 million eggs. Indigenous this time, no new eggs are produced. In ~ birth, over there are roughly 1 million eggs; and also by the moment of puberty, only around 300,000 remain. That these, just 300 to 400 will certainly be ovulated during a woman's reproductive lifetime. Fertility deserve to drop together a woman ages because of decreasing number and quality the the continuing to be eggs.
