The Female Reproductive System

The female reproductive system is designed to carry out several functions. It produces the feminine egg cells necessary for copy, known as the ova or oocytes. The system is meant to move the ova to the positioning of fertilization. Conception, the fertilization of associate degree egg by a sperm, commonly happens within the fallopian tubes. succeeding step for the beast is to implant into the walls of the womb, starting the initial stages of physiological state. If fertilization and/or implantation doesn’t occur, the system is meant to shed blood (the monthly shedding of the female internal reproductive organ lining). additionally, feminine|the feminine} system produces female sex hormones that maintain the procreative cycle.

What Parts Make up the Female Anatomy?

The female reproductive anatomy includes parts inside and outside the body.The operate of the external feminine procreative structures (the venereals) is twofold: To alter sperm cell to enter the body and to guard the interior genital organs from infectious organisms. the most external structures of the feminine genital system include:

The labium enclose and shield the opposite external generative organs. virtually translated as “large lips,” the labium ar comparatively giant and fleshy, and ar admire the pouch in males. The labium contain sweat and oil-secreting glands. once time of life, the labium ar lined with hair.

Labia minora

Literally translated as “small lips,” the labium will be terribly little or up to a pair of inches wide. They lie simply within the labium, and surround the openings to the channel (the canal that joins the lower a part of the womb to the surface of the body) and canal (the tube that carries pee from the bladder to the surface of the body).

These glands are located beside the vaginal opening and produce a fluid (mucus) secretion.

The two labium meet at the button, a small, sensitive protrusion that’s akin to the erectile organ in males. The button is roofed by a fold of skin, known as the prepuce, that is analogous to the foreskin at the tip of the erectile organ. just like the erectile organ, the button is extremely sensitive to stimulation and might become erect.

The internal reproductive organs in the female 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 womb may be a hollow, pear-shaped organ that’s the house to a developing vertebrate.The womb is split into 2 parts: the cervix, that is that the lower half that opens into the epithelial duct, and also the main body of the womb, referred to as the corpus. The corpus will simply expand to carry a developing baby.A channel through the cervix permits spermatozoon 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

Fallopian tubes

These square measure slender tubes that square measure connected to the higher a part of the female internal reproductive organ and function tunnels for the ova (egg cells) to travel from the ovaries to the female internal reproductive organ. Conception,the fertilization of associate egg by a sperm cell, commonly happens within the fallopian tubes. The animal then moves to the female internal reproductive organ, wherever it implants into the liner of the female internal reproductive organ wall.

What Happens During the Menstrual Cycle?

Menstrual Cycle

Females of procreative age expertise cycles of secretion activity that repeat at concerning one-month intervals. With each cycle, a female body prepares for a possible physiological state, whether or not or not that’s the woman’s intention. The term menses refers to the periodic shedding of the female internal reproductive organ lining. (Menstru means that “monthly.”)

The average oscillation takes concerning 28 days and happens in sections: the cyst phase, the the ovulatory phase (ovulation), and therefore the secretory phase.

There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) concerned within the expelling cycle: follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone.

Follicular Phase of the Menstrual Cycle

Follicular phase – early and late diagram

This part starts on the primary day of your amount. throughout the vesicle part of the cycle, the subsequent events occur:
*Two hormones, vesicle stimulating endocrine (FSH) and luteinizing hormone (LH), area unit discharged from the brain and travel within the blood to the ovaries.
*The hormones stimulate the expansion of concerning 15 to 20 eggs within the ovaries, every in its own “shell,” referred to as a vesicle.
*These endocrines (FSH and LH) additionally trigger a rise within the production of the feminine hormone steroid hormone.
*As steroid hormone levels rise, sort of a switch, it turns off the production of follicle-stimulating hormone. This careful balance of hormones permits the body to limit the quantity of follicles that mature.
*As the vesicle part progresses, one vesicle in one ovary becomes dominant and continues to mature. This dominant vesicle suppresses all of the opposite follicles within the cluster. As a result, they stop growing and die. The dominant vesicle continues to supply steroid hormone.

Ovulatory Phase of the Menstrual Cycle

Menstrual cycle

The ovulatory section, or organic process,starts regarding fourteen days when the vesicle section started. The ovulatory section is that the center of the cycle, with the next menstrual period starting about two weeks later. During this phase, the following events occur:
*The rise in estrogen from the dominant vesicle triggers a surge within the quantity of luteinizing hormone that’s created by the brain.
*This causes the dominant vesicle to unleash its egg from the ovary..
*As the egg is free (a method known as ovulation),it is captured by finger-like projections on the tip of the fallopian tubes (fimbriae). The fimbriae sweep the egg into the tube.
*Also throughout this section, there’s a rise within the quantity and thickness of mucous secretion created by the cervix (lower a part of the uterus). If a girl were to possess intercourse throughout now, the thick mucous secretion captures the man’s gamete, nourishes it, and helps it to maneuver towards the egg for fertilization.

Luteal Phase of the Menstrual Cycle

The stage of the cycle begins right when biological process and involves the subsequent processes:
*Once it releases its egg, the empty cyst develops into a brand new structure referred to as the ductless gland.
*The corpus luteum secretes the hormone progesterone. Progesterone prepares the uterus for a fertilized egg to implant.
*If intercourse has taken place and a man’s sperm cell has inseminated the egg (a method referred to as conception), the animal (embryo) can travel through the oviduct to implant within the female internal reproductive organ. the lady is currently thought of pregnant.
*If the egg isn’t inseminated, it passes through the female internal reproductive organ. Not required to support a gestation, the liner of the female internal reproductive organ breaks down and sheds, and therefore the next discharge amount begins.

The overwhelming majority of the eggs inside the ovaries steady die, till they’re depleted at climacteric. At birth, there are more or less one million to two million eggs; by the time of pubescence, solely regarding 300,000 remain. Of these, solely regarding 500 are going to be ovulated throughout a woman’s generative period. Any remaining eggs bit by bit die out at climacteric.
