menstrual cycle
Do you know the functions of female reproductive system?
1. The ovary releases egg cell for fertilisation.
2. It also secretes some hormones to make changes in the uterus
3. The uterus gets prepared to host the embryo till it completely grown into a baby.

once the egg is released by the ovary, the hormones secreted by the ovary makes the uterus wall thick, and lined by blood and mucous. This would be required for nourishing the embryo if fertilization had
taken place.

If the egg is fertilized, it gets implanted in the cushioning of the uterus.

What happens if the egg is not fertilized?

If the egg is not fertilised, it lives for about one day. Then the blood lining of the uterus is no longer needed. Because if there is no fertilisation there will be no implantation.

So lining of blood along with mucous sheds out through the vagina. It may take two to eight days.
This cycle of events takes place every month periodically and is called menstruation . The span of menstrual cycles is about 28 days.

When do the menstruation begins in girls.

A girl can start her period anytime between the ages of 8 and 15. It all depends on the genetics and other factors.

That’s all about the menstrual cycle.
