What is menstruation? Explain.

 

Answer

Bleeding from uterus is called menstruation

It occurs every month in woman

It begins from puberty till the age of 45-50 years

 

Reason for Menstruation

When females reach puberty, they develop ovaries

Ovaries release ovum (egg)

One ovum matures once in a month (28-30 days)

Uterus develops a thick wall to receive fertilised egg

If this ovum is fertilized by egg,it leads to pregnancy

If it is not fertilized,the egg ,thick lining of uterus and blood vessel are shed by body

This leads to bleeding and is called menstruation
