Question

What changes are absorbed in the uterus if fertilization does not occur?

Answer 1

Explanation:

Every month, the uterus prepares itself to receive a fertilised egg. Therefore, the inner lining of the uterus becomes thick and is supplied with blood to nourish the embryo. If the egg is not fertilised, then the lining of the uterus breaks down and gets released in the form of blood through the vagina.
