why meansuration occur ?​

Answer 1

Explanation:

A period releases the tissue that grew to support a possible pregnancy. It happens after each menstrual cycle in which a pregnancy doesn't occur—i.e. when an egg hasn't been fertilized and/or attached itself to the uterine wall. The uterus then sheds the lining which had grown to receive a fertilized egg.
