How does the mrs reproductive system work?

The woman reproductive system gives several functions. The ovaries create the egg cells, dubbed the ova or oocytes. The oocytes room then transported to the fallopian tube where fertilization through a sperm may occur. The fertilized egg climate moves come the uterus, wherein the uterine lining has thickened in an answer to the common hormones of the reproductive cycle. Once in the uterus, the fertilized egg have the right to implant into thickened uterine lining and also continue come develop. If implantation does no take place, the uterine lining is shed as menstrual flow. In addition, the woman reproductive system produces woman sex hormone that preserve the reproductive cycle.

During menopause, the mrs reproductive system gradually stops make the woman hormones important for the reproductive cycle come work. In ~ this point, menstrual cycles can end up being irregular and eventually stop. One year ~ menstrual cycles stop, the mrs is taken into consideration to be menopausal.

What parts make-up the female

The woman reproductive consists of both external and internal structures.

The duty of the outside female reproductive structures (the genital) is twofold: To permit sperm to go into the body and to safeguard the interior genital guts from infectious organisms.

The main outside structures that the mrs reproductive system include:

Labia majora: The labia majora (“large lips”) enclose and protect the other external reproductive organs. Throughout puberty, hair expansion occurs top top the skin of the labia majora, which additionally contain sweat and also oil-secreting glands.Labia minora: The labia minora (“small lips”) can have a variety of sizes and shapes. Castle lie simply inside the labia majora, and surround the openings to the vagina (the canal the joins the lower component of the uterus come the external of the body) and urethra (the tube that carries urine from the bladder to the external of the body). This skin is an extremely delicate and also can become easily irritated and also swollen.Bartholin’s glands: these glands are located next come the vaginal opening on every side and also produce a fluid (mucus) secretion.Clitoris: The 2 labia minora meet at the clitoris, a small, sensitive protrusion the is comparable to the dick in males. The clitoris is spanned by a fold of skin, referred to as the prepuce, i m sorry is similar to the foreskin in ~ the finish of the penis. Choose the penis, the clitoris is really sensitive come stimulation and can come to be erect.


The interior reproductive organs include:

Vagina: The vagina is a canal the joins the cervix (the lower part of uterus) to the outside of the body. It likewise is well-known as the bear canal.Uterus (womb): The uterus is a hollow, pear-shaped body organ that is the residence to a arising fetus. The uterus is divided into two parts: the cervix, i m sorry is the lower component that opens right into the vagina, and the main body the the uterus, referred to as the corpus. The corpus can quickly expand to hold a occurring baby. A canal through the cervix enables sperm to enter and menstrual blood to exit.Ovaries: The ovaries are small, oval-shaped glands the are located on either next of the uterus. The ovaries create eggs and also hormones.Fallopian tubes: These room narrow tubes that are attached to the upper part of the uterus and also serve together pathways because that the ova (egg cells) to travel from the ovaries to the uterus. Fertilization of one egg through a sperm generally occurs in the fallopian tubes. The fertilized egg then moves come the uterus, wherein it implants come the uterine lining.


What happens throughout the term cycle?

Females that reproductive age (beginning everywhere from 11 come 16 year of age) endure cycles that hormonal task that repeat at about one-month intervals. Menstru means "monthly” – bring about the term menstrual cycle. Through every cycle, a woman’s human body prepares because that a potential pregnancy, whether or no that is the woman’s intention. The ax menstruation refers to the periodic shedding of the uterine lining. Countless women call the days that they an alert vaginal bleeding their “period,” “menstrual” or cycle.

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

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


There space four significant hormones (chemicals the stimulate or regulate the task of cell or organs) involved in the expression cycle. This hormones include:

Follicle-stimulating hormoneLuteinizing hormoneEstrogenProgesterone

Follicular phase

This phase starts ~ above the first day of your period. Throughout the follicular step of the expression cycle, the following occasions occur:

Two hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH) are released indigenous the brain and take trip in the blood to the ovaries.The hormones stimulate the growth of around 15 come 20 eggs in the ovaries, every in its own "shell," dubbed a follicle.These hormone (FSH and LH) likewise trigger boost in the production of the mrs hormone estrogen.As estrogen level rise, favor a switch, it transforms off the manufacturing of follicle-stimulating hormone. This cautious balance the hormones enables the human body to limit the variety of follicles that will prepare eggs to it is in released.As the follicular step progresses, one follicle in one ovary becomes dominant and continues to mature. This dominant follicle suppresses every one of the other follicles in the group. As a result, they stop 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, but this can vary. The ovulatory step falls between the follicular phase and luteal phase. Many women will have actually a menstrual duration 10 to 16 job after ovulation. Throughout this phase, the following occasions occur:

The climb in estrogen from the dominant follicle root cause a rise in the lot of luteinizing hormone that is created by the brain.This causes the dominant follicle to release its egg from the ovary.As the egg is exit (a procedure called ovulation) the is recorded by finger-like projections top top the finish of the fallopian pipe (fimbriae). The fimbriae move the egg right into the tube.For one to five days prior to ovulation, many women will notification an boost in egg white cervical mucus. This rubber is the vaginal discharge that helps to capture and also nourish sperm top top its means to meet the egg because that fertilization.

Luteal phase

The luteal phase begins right ~ ovulation and involves the adhering to processes:

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

How countless eggs go a mrs have?

During fetal life, over there are about 6 million to 7 million eggs. Native this time, no brand-new eggs room produced. In ~ birth, there are approximately 1 million eggs; and by the moment of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime. Fertility deserve to drop as a mrs ages as result of decreasing number and also quality that the continuing to be eggs.
