explain menstruation cycle in female
Answers
Explanation:
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. Women begin menstruation at an average age of 13 (called menarche) and on average continue menstruating till age 51 (called menopause).
Answer:
1. The menstrual cycle is the regular natural change that occurs in the female reproductive system (specifically the uterus and ovaries) that makes pregnancy possible.
2. The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy. The menstrual cycle occurs due to the rise and fall of estrogen.
3. This cycle results in the thickening of the lining of the uterus, and the growth of an egg, (which is required for pregnancy).
4. The egg is released from an ovary around day fourteen in the cycle; the thickened lining of the uterus provides nutrients to an embryo after implantation.If pregnancy does not occur, the lining is released in what is known as menstruation or a "period".
