Answer 2

Answer:

Hii... here is your answer

Explanation:

Answer: In females, one egg is released from one ovary every month. Every month, the uterus prepares itself to receive the embryo in case fertilization occurs. Hence, to discard the unwanted uterine endometrial lining and the ovary which is not fertilized the menstruation occurs in human females.
