Answers & Comments
Answer:
5. Embedded in this lining are glands that can secrete a fluid that will help nourish a pregnancy until a placenta is formed. In a typical menstrual cycle, estrogen made by the maturing ovarian follicle causes the glands to grow and the endometrium to thicken (partly through an increased blood supply).
6.Ovulation is when a mature egg is released from one of your ovaries. If you ovulate and a sperm cell doesn't successfully fertilize the egg, the egg will simply move down the fallopian tube, through the uterus, and out through the vagina. You'll menstruate about two weeks later when the uterus lining is shed.
