What is menstrual cycle explain ?
Dear Student, The menstrual cycle is the reproductive cycle in a human female after puberty. The ovary releases one egg every month. The uterus also prepares itself every month to receive a fertilized egg. The inner uterus lining becomes thick and is supplied with blood to nourish the embryo. If the egg is not fertilized, then the uterus lining breaks down and is released in the form of blood and mucous through the vagina. This process lasts for 2-8 days. This cycle occurs every month and is known as menstruation. This cycle is normally of 28 days but it varies from woman to woman. Regards
If the ovum (or egg) does not get fertilised ( due to non-availability of sperm in the female body) then the thick and soft inner lining of uterus is no longer needed and hence, it breaks. So, the thick and soft inner lining of uterus alongwith the blood vessels and the dead ovum (or egg) comes out of the vagina in the form of blood called menstruation. Menstruation occurs after the interval of energy 28 days and the time period between ovulation and menstruation is about 14 days.
