Answer :
The monthly flow of tissue and blood as a self-cleansing process in females is called Menstruation.
The endometrium, which lines the uterus, sheds during the menstrual phase of the female reproductive cycle. Throughout a woman's reproductive life, this happens. The menstrual blood is made up of both blood and tissue from the uterus. The vagina is where it exits the body. Periods typically begin between the ages of 11 and 14 and last until menopause, which occurs at around age 51. Typically, they last three to five days. Increased amounts of progesterone and estrogen contribute to the walls' thickening. The menstrual flow, which leaves the body through the vagina during the period if fertilization is unsuccessful, is made up of the endometrium, blood, and mucus from the vagina and cervix.
