Question

4. Why does menstrual cycle take place every month in a human female?​

Answer 1

Answer:

As a woman, your period is your body's way of releasing tissue that it no longer needs. Every month, your body prepares for pregnancy. The lining of your uterus gets thicker as preparation for nurturing a fertilized egg. An egg is released and is ready to be fertilized and settle in the lining of your uterus.

Answer 2

Answer:

As a woman, your period is your body’s way of releasing tissue that it no longer needs. Every month, your body prepares for pregnancy. The lining of your uterus gets thicker as preparation for nurturing a fertilized egg. An egg is released and is ready to be fertilized and settle in the lining of your uterus.

If the egg is not fertilized, your body no longer needs the thicker lining of the uterus, so it starts to break down and is eventually expelled, along with some blood, from your vagina. This is your period, and once it’s over, the process starts all over again.
