Next, I will introduce them one by one for your reference.

　　Why do girls menstruate?

　　Generally speaking, the menstrual period means that a mature woman has her menstruation once every month, which is the menstrual period. Generally, a girl takes about 3 days to 7 days. During this period, the girl’s Uterus A certain amount of blood is discharged through the vagina, and this blood is very clean. During this period, you should be careful not to be too tired, not eat raw or cold food, keep your mood comfortable, and pay attention to keeping clean.

　　First, we must understand the structure and physiological functions of female reproductive organs in order to explain this problem. The female internal reproductive organs consist of the ovaries, uterus, and fallopian tubes. The main function of the ovaries is to produce eggs and synthesize ovarian hormones. The uterus and fallopian tubes are reproductive organs. The ovaries contain hundreds of thousands of follicles, each of which contains one egg.

　　Follicles are essentially nonfunctional before puberty. During puberty, under the action of gonadotropins from the anterior pituitary gland, immature follicles gradually develop and simultaneously synthesize estrogen. When the follicle matures and ovulates, the egg wall collapses and the cells become larger and yellower, called the corpus luteum, which not only synthesizes estrogen but also produces progesterone. As the ovaries change, the endometrium is affected by them and undergoes corresponding cyclic changes. Estrogen causes the endometrium to thicken, endometrial cells increase and enlarge, and the tubes become more tortuous and spiral-shaped, which is called the proliferative endometrium.

　　After ovulation, due to the combined action of estrogen and progesterone, the endometrium becomes edematous, the glands produce a large amount of mucus and glycogen, and the thickness of the endometrium increases from 1 mm to 6 mm, which is called the secretory phase endometrium. If the egg discharged at this time is fertilized, the fertilized egg will be transported to the uterus through the fallopian tube to develop, which is called pregnancy. The pregnancy tissue synthesizes a chorionic gonadotropin, which supports the continued development of the corpus luteum of the ovary. ； If the egg is not fertilized, the corpus luteum atrophies and stops secreting estrogen and progesterone about 14 days after ovulation. At this time, the blood vessels in the endometrium contract and the endometrium becomes necrotic and falls off, causing bleeding and menstruation.
