1. Breast: Breast is mainly composed of glands, ducts, adipose tissue and fibrous tissue. Its internal structure is like a small tree growing upside down. Breast glands are composed of 15-20 glandular lobes, each glandular lobe is divided into several glandular lobules, and each glandular lobule is composed of 10-100 acinars.
These acini are closely arranged around the small milk ducts, the openings of which connect to the small milk ducts. Multiple small milk ducts merge into interlobular milk ducts, and multiple interlobular milk ducts further merge into a whole glandular lobe of breast ducts, also known as lactiferous ducts. There are 15-20 lactiferous ducts in total, which are arranged radially with the nipple as the center.
The mammary duct openings are stratified squamous epithelium, the stenosis is transitional epithelium, the ducts below the ampulla are double-layered columnar epithelium or single-layered columnar epithelium, the terminal duct near the acinar is cuboidal epithelium, and the acinar Lined with cubic epithelium.
2. Vagina: The vagina is located in the center of the lower part of the true pelvis, which is the channel for the sexual organs and the discharge of menstrual blood and the delivery of the fetus. The vagina is a muscular tube with a slightly flat front and rear. The upper end surrounds the cervix. The part surrounding the cervix is called the vaginal fornix, which can be divided into four parts: anterior, posterior, left, and right. The concave is the lowest position of the abdominal cavity, and the posterior fornix is the main part of the accumulation of semen after sexual intercourse, and is called the vaginal cistern, which is conducive to the entry of sperm into the uterine cavity.
The vaginal mucous membrane is light red and has no glands. Under normal circumstances, white transparent or translucent vaginal fluid flows out of the vagina, that is, leucorrhea. It is composed of the secretions of cervix glands, endometrial glands, vaginal mucosal exudates and epithelial cells shed from the vaginal wall. The main function of leucorrhea is to maintain lubrication in the vagina. Pleasure and the entry of sperm into the uterine cavity are of great significance in promoting a woman's conception.
The vagina itself has a self-cleaning effect, this is because the vaginal epithelial cells are rich in glycogen, which is produced by the decomposition of vaginal bacteria parasitic in the vagina to produce lactic acid. Lactic acid creates an acidic environment in the vagina, which prevents the reproduction of many pathogenic bacteria.
3. Hymen: The hymen is located at the boundary between the vaginal opening and the vaginal vestibule. It is a thin film-like tissue with holes in the middle that surrounds the vaginal opening. There is a hole or porous in the middle, called the hymen hole. Most of the holes are annular, oval, half-moon-shaped or irregular cracks; the holes are sieve-shaped.
The size of the hymen hole and the thickness of the membrane may vary from person to person. The diameter of the hymen hole is about 1-1.5 cm, usually round, oval or zigzag; some are half-moon-shaped, and the membrane hole is on one side; some are septate holes, with two small holes for upper and lower or Side by side; some have many scattered holes, like the holes in a sieve.
The hymen can prevent unclean things from entering the vagina and protect the vagina. The hymen hole is necessary for physiology. After a woman matures, the monthly menstrual blood is excreted through this small hole. If there is no small hole in the membrane, the monthly menstrual blood is blocked by it and cannot be excreted from the body. It is called in medicine. Hymen atresia.
4. Uterus: The uterus is located in the center of the pelvic cavity, in an inverted pear shape, with a flat front and a slightly protruding back. The adult uterus is about 7-8cm long, 4-5cm wide, 2-3cm thick, and the uterine cavity capacity is about 5ml. . The upper part of the uterus is wider, called the uterus, and the protruding part at the upper end is called the uterine fundus. The lower part of the uterus is narrow and cylindrical, called the cervix.
The uterus is a hollow organ, and the cavity is covered with mucous membranes, called the endometrium. From puberty to menopause, the endometrium is affected by ovarian hormones, which undergo periodic changes and produce menstruation. During sexual intercourse, the uterus is the passage for sperm to reach the fallopian tubes.
After conception, the uterus is the place where the embryo develops and grows. During labor, the uterus contracts, allowing the fetus and its appendages to be delivered. The uterine cavity is a triangle with a wide upper and a lower narrow, forming the narrowest part between the uterine body and the cervix, called the uterine cheek. In non-pregnant period, it is about 1cm long, and its lower end is connected to the cervical cavity.
The inner cavity of the cervix is prismatic and is called the cervical canal. In adult women, it is about 3cm long, and its lower end is called the external cervical orifice and connects to the top of the vagina.
