Menstruation is the process of shedding the uterine lining on a regular monthly basis in women. It is a part of the menstrual cycle, which is a series of changes that occur in a womans body in preparation for the possibility of pregnancy. The menstrual cycle is controlled by hormones, and it typically lasts around 28 days.
During menstruation, the uterus wall breaks down and the blood vessels in the uterus rupture, leading to the release of blood and other materials through the vaginal canal. Menstruation usually lasts for around 3-7 days, but it can vary from woman to woman.
Menstruation starts at puberty and is a part of the reproductive cycle of women. It is a normal and natural process that occurs in the female body.
