What is menstruation?

Menstruation describes the female period. The menstruation cycle begins when a woman gets her periods. The menstrual blood which leaves her body are products shed from the uterus (the uterine lining also called the endometrium). During the remainder of the menstrual cycle the uterine lining regrows. It does so in preparation for pregnancy, which occurs if the egg (oocyte) a woman releases about half way through her menstrual cycle is fertilised. When fertilisation occurs, the lining stays in place to nourish the fertilised egg. When fertilisation does not occur the menstrual cycle continues and the uterine lining is shed marking the start of the woman’s next menstrual period.

Answer 2

Answer:

The menstruation cycle refers to the cycles in which a woman’s uterus grows and sheds a lining (the endometrium) which could support the development of a fertilised egg. It typically occurs in 28 day cycles, so a woman generally gets her period every 28 days. However, cycle length may be as short as 21 days or as long as 40 days in some women. The inner lining of the uterus (the endometrium) goes through three phases during the typically 28 day menstrual cycle: the menstrual phase (days 1-5), the proliferative phase (days 6-14) and the secretory phase (days 15-28).
