Answer 1

Menstruation:

1. Menstruation is the process of the shedding of the uterine lining on a regular monthly basis in women.
2. Menstruation is triggered by an abrupt decline in the amount of a hormone secreted by the corpus luteum.
3. When an ovary at ovulation releases an egg, during the menstrual cycle, the ovarian follicle's remnants enclose the developing egg forming the corpus luteum.
4. The hormone released by the corpus luteum is progesterone.
5. It plays a very essential role in the menstrual cycle.
6. It helps to maintain the pregnancy's early stages.
7. Progesterone helps in preparing for pregnancy only if the egg released is fertilized.
8. The egg released, if not fertilized, progesterone production falls, breaking down the corpus luteum, and resulting in the beginning of a fresh menstrual cycle.
