Question

expain menstrual cycle???

Answer 1

Menstruation (men-STRAY-shuhn) is a woman's monthly bleeding. When you menstruate, your body sheds the lining of the uterus (womb). Menstrual blood flows from the uterus through the small opening in the cervix and passes out of the body through the vagina. Most menstrual periods last from 3 to 5 days.

Answer 2

Menstrual cycle is a sign that now the female body is ready for fertilization. Every month, the internal organs of the body squeeze out dead material from uterus which was prepared for pregnancy. It indicates that fertilization has not occurred this month hence it removes the dead material.
