Question 11

What is menstruation?

Answer 11

The process of shedding the uterine lining on a regular monthly basis is called menstruation.
It starts at puberty and in the reproductive cycle of the female body. The uterus prepares itself to
receive a fertilized egg every month. Due to this, the inner lining of the uterus becomes thick and is
supplied with blood to nourish the embryo. If the egg is not fertilized, then the lining of the uterus
breaks down and gets released in the form of blood through the vagina. The time period for this is
about 2 to 8 days every month. This monthly cycle is known as the menstrual cycle.
