How much do you know about the structure of the vagina?

As we enter the dog days of summer, many female diseases begin to bother us, such as vaginal itching, candidal vaginitis, etc. Vaginal health has gradually attracted everyone's attention. Especially for middle-aged women, as a high-risk group for vaginal diseases, they should be given enough attention and attention. When talking about vaginal health, how many people know the most basic knowledge about the structure of the vagina and basic vaginal care? Next, I will give you a general introduction to the structure of the vagina, laying a solid foundation for better prevention and treatment of vaginal diseases.

The vagina is a muscular tube composed of mucosa, muscular layer and outer membrane. It is highly elastic and connects the uterus and external genitalia. It is the female's sexual organ and also the channel for discharging menstruation and delivering the fetus. Commonly known as cunt.

The vagina is a flat muscular tube composed of mucosa, muscle layer and outer membrane. It is highly elastic and connects the uterus and external genitalia. It is a coital organ where semen is retained and coagulated. The dilated vagina is a storage site for semen after sexual intercourse, providing a reservoir for the cervix. The vaginal folds and the rhomboid-shaped muscle layer enable the vagina to expand during sexual intercourse and childbirth. Although the vagina does not contain glands, the vaginal wall can be kept warm by the secretions of the vaginal epithelium, cervical mucus and endometrial secretions.

The posterior vaginal fornix is ​​the lowest part of the vagina in the bladder cross-section. This anatomical position makes it easier to transport sperm from the vagina to the cervix, because the normally positioned external cervical opening faces the posterior fornix of the vagina, which is the most dilatory part of the vagina and provides a suitable space for erection.

The narrow vaginal canal and the chemical and microbial environment of the vagina prevent microorganisms from invading the internal reproductive tract. The vagina is also the discharge channel for menstrual bleeding and secretions from the cervix and endometrium, and it is also the birth canal during normal delivery. These functions are accomplished through the vagina's various physiological characteristics, such as contraction, expansion, secretion and absorption.

The hymen is attached around the vaginal opening of a virgin. There is a hole in the middle of the hymen. The size of the hole and the shape and thickness of the membrane vary from person to person. After rupture, a hymen mark will be left around the vaginal opening.

The vagina is a muscular tube composed of mucosa, muscle layer and outer membrane. It is highly stretchable, with the upper end surrounding the cervix and the lower end opening in the vaginal vestibule, connecting the uterus and external genitalia. The annular space formed between the cervix and the vaginal wall is called the vaginal vault. The vaginal vault can be divided into anterior, posterior, left and right parts. The posterior part of the vaginal vault is deeper and is adjacent to the rectouterine pouch. The anterior wall of the vagina is short, about 6 to 7 cm long. The upper part is adjacent to the base and neck of the bladder through the vesicovaginal septum, and the middle and lower parts are adjacent to the urethra through the urethrovaginal septum. The posterior wall of the vagina is relatively long, about 7.5 to 9 cm long. The upper part is adjacent to the rectouterine pouch, the middle part is adjacent to the rectal ampulla through the rectovaginal septum, and there is a perineal central tendon between the lower part and the anal canal. Section 3 Perineum The perineum refers to all the soft tissues below the pelvic diaphragm that close the lower opening of the pelvis, that is, the perineum in a broad sense. It is diamond-shaped, with its border consistent with the lower opening of the pelvis, the lower edge of the pubic symphysis and the pubic arcuate ligament in front, the pubic arch, ischial tuberosity and sacrotuberous ligament on both sides, and the tip of the coccyx in the back. The perineum can be divided into the urogenital area in the front and the anal area in the back through the line connecting the ischial tuberosities on both sides.

The above is a detailed explanation of the structure of the vagina. Is everyone clear about it? From the above detailed explanation, it can be seen that in addition to being an important sexual organ of the human body, the vagina also has certain functions of protecting the body. The vagina itself is slightly acidic, and the lactobacilli inside it protect the body from invasion and infection by external bacteria.
