Expert Answer:

  • The ovary releases one egg every month.
  • The uterus also prepares itself every month to receive a fertilized egg.
  • The inner uterus lining becomes thick and is supplied with blood to nourish the embryo.
  • If the egg is not fertilized, then the uterus lining is not required.
  • Hence, it breaks down and is released in the form of blood and mucous through the vagina.
  • This process lasts for 2-8 days. This cycle occurs every month and is known as menstruation which are often referred to as periods.
