The female physiology, in general, refers to the organs of female characteristics, namely the female genitalia and breasts. Female genitalia include external genitalia and internal genitalia. 1, the external genitalia refers to the exposed part of the reproductive organs, also known as vulva, including the mons pubis, labia majora, labia minora, clitoris and vaginal vestibule. The pubic mound: the skin bulge located in front of the pubic symphysis, the growth of pubic hair in an inverted triangular distribution. (Is it okay to cut pubic hair? (Not recommended) Labia majora: a pair of longitudinal elevated skin folds on the inner side of the two femurs, prone to hematoma formation after trauma. (The vulva is very fragile, so try to avoid external damage) Labia minora: a pair of thin skin folds on the inside of the labia majora on both sides. Clitoris: consists of two clitoral spongiosomes, rich in nerve endings and sensitive to sexual stimulation. Vaginal vestibule: contains five structures: vestibular bulb, vestibular gland, urethral opening, vaginal opening, and hymen. The vestibular glands secrete mucus to lubricate the vagina during sexual arousal. The perimeter of the vaginal opening is covered with a thin layer of mucosal folds called the hymen, mostly with a hole in the center, round or crescent-shaped, the size of which varies greatly from small enough to pass a finger to large enough to hold two fingers, and even some women do not have a hymen. (So, no hymen does not mean not a virgin!) 2, female internal genitalia, including the vagina, uterus, fallopian tubes and ovaries. The ovaries: there is one ovary on each side of the uterus, which is where the follicles grow and develop, and where the hormones that maintain female characteristics are secreted, and after menopause, the ovaries gradually shrink. Fallopian tubes: the place where the egg and sperm meet and unite, and the channel for transporting the fertilized egg. Uterus: The organ that nurtures the embryo, the fetus and produces menstruation. It is inverted and pear-shaped in the center of the pelvis. In most women, the uterus is in an anteverted position and is about the size of an egg when it is not pregnant. In addition, some women are born with abnormal uterine development, such as a longitudinal uterus or a bicornuate uterus. The vagina is an organ of sexual intercourse and a channel for the discharge of menstrual blood and the delivery of the fetus. The breasts, which are the second female sex characteristics, consist of skin, fatty tissue, fibrous tissue and mammary glands. At the end of pregnancy, the mammary glands begin to secrete a small amount of milk, and after the delivery of the fetus, the amount of milk increases as the baby grows up, and after breastfeeding stops, the glands in the breast gradually shrink and become smaller.
