Reproductive system diagram

The female reproductive organs include mons pubis, labia majora, labia, clitoris, vaginal vestibule, Bartholin's glands, vulva, and ruptured hymen. The hymen is located at the junction of the vulva and the vestibule of the vagina. It is a plastic film with a hole in the center. It is ring-shaped or half-moon-shaped, and its thickness varies from person to person. The hymen is usually torn during the first sexual intercourse, and only remnants are left after a pregnant woman gives birth. But some women are born without a hymen, or it is torn during excessive exercise.

The female internal reproductive organs include the uterus, ovaries, bilateral fallopian tubes, uterus, and vagina. The uterus and ovaries produce and release eggs and secrete estrogen; the fallopian tubes can transport eggs and sperm and are the site of fertilization; the uterus is the organ that creates and delivers the fetus; the vagina is the sexual organ and is the passage for menstrual discharge and fetal delivery.

Reproductive organs

1. The scope of private parts

The female reproductive organ refers to the exposed part of the male reproductive organ, also known as the private parts, which refers to the tissue between the ischial tuberosity to the perineum and the inner side of the thighs.

2. The composition of private parts

(1) The mons pubis is located in front of the ischial tuberosity, and the subcutaneous tissue is rich in adipose tissue. At the beginning of puberty, the skin above the pubic area begins to grow curly pubic hair, which is one of the secondary sexual characteristics.

(2) The labia majora are a pair of raised skin folds on both sides of the private parts. It connects to the mons pubis in front and the perineum in the back. The subcutaneous tissue of the labia majora contains human fat tissue and venous plexus, which are prone to abscesses after some injuries.

(3) The labia majora are located inside the labia majora. It is a pair of longitudinal skin folds with a moist surface similar to mucous membrane, brown in color, hairless, and containing peripheral nerves, so it is extremely sensitive.

(4) The clitoris is located at the front of the labia majora. It is the cavernous tissue of the penis, and the glans clitoris contains peripheral nerves and is extremely sensitive.

(5) The vaginal vestibule is the angular area between the two labia. There is the urethral opening just in front of the vestibular function, and the vaginal opening just behind it.

Internal genitalia

The female internal reproductive organs include the vagina, uterus, bilateral fallopian tubes and uterus and ovaries, the latter two are called appendages.

1. Intravaginal

It is a safe passage for the discharge of sexual organs, menstrual blood and the delivery of the fetus.

2. The Palace

A human organ with thick walls, small cavities, and dominated by muscles. The mucous membrane covering the cavity is called the uterine wall. After puberty, it is affected by estrogen to produce regular changes and cause menstruation; during pregnancy, it creates a fetus.

3. Bilateral fallopian tubes

The bilateral fallopian tubes are the place where the egg cell and the male sperm meet, and are also the pipelines for transporting sperm and egg to the uterine cavity for combination. It is a pair of long, thin and curved tubes located within the inner edge of the platysma tendon of the uterus. The inner side is connected to the uterine horn, and the toe is mineral acid, close to the uterus and ovaries. About 8 to 14 cm long. According to the shape of the bilateral fallopian tubes, they can be divided into four parts from the inside to the outside: the interstitial part, the muscular wall, the ampulla and the fimbria.

The walls of both fallopian tubes are composed of three layers: the surface layer is the serosa layer, the middle and high layers are the smooth muscle layer, and the inner layer is the mucosal layer. The inner layer contains microvilli somatic cells, the movement of which facilitates the transport of egg cells.

4. Uterus and ovaries

It is a pair of flat oval sex hormones that have reproductive and endocrine functions, produce and release eggs, and secrete estrogen. Before puberty, the surface of the uterus and ovaries is smooth; after the beginning of ovulation during puberty, the surface gradually becomes uneven; the uterus and ovaries of adult women are about 4cm x 3cm x 1cm in size, weigh 5 to 6g, and are grayish white; after menopause, the ovaries shrink, become hard, and shrink. The uterus and ovaries are connected to the pelvic wall on both sides by the pelvic Brugge infundibulum tendons, and the inner side is connected to the uterus by the original tendons of the uterus and ovaries.
