1.	Describe in brief the change that uterus undergoes 1. To receive the zygote2. If zygote is not fomed
Answer» (i) The uterus prepares itself every month to receive a fertilized egg/zygote- The inner uterus lining (endometrium) becomes thick and is supplied with blood to nourish the embryo.(ii) If the egg is not fertilized, then the uterus lining is not required. Hence, it breaks down and gets released in the form of blood and mucus through the ******. This process lasts for 2-8 days. This cycle occurs every month and is known as menstruation.
