I don't know if this is a true or false because there is no question.
1. Ovulation.
Ovulation is the release of a mature egg from the surface of the ovary. This usually occurs mid-cycle, around two weeks or so before menstruation starts. During the follicular phase, the developing follicle causes a rise in the level of oestrogen.
2. When the follicular phase begins, levels of estrogen and progesterone are low. As a result, the top layers of the thickened lining of the uterus (endometrium) break down and are shed, and menstrual bleeding occurs. ... This follicle produces estrogen.
3. When the egg becomes fully mature, the follicle surrounding the egg bursts, and releases a mature egg which travels through the fallopian tube toward the uterus. The egg is capable of being fertilized for a short period, about 48 hours. ... This is the period of life known as menopause.
4. Increasing amounts of estrogen stimulate a thickening of the lining of the uterus, known as the endometrium. This can be thought of as growing a thick, lush lawn, but instead of a lawn, you're growing a nutrient-rich uterine lining in preparation to receive a fertilized egg.
5. Ovulation occurs mid-cycle. In the ovary, all eggs are initially enclosed in a single layer of cells known as a follicle, which supports the egg. Over time, these eggs begin to mature so that one is released from the ovary in each menstrual cycle.
6. A menstrual cycle starts with the first day of the period and ends with the start of the next period. An entire menstrual cycle usually lasts between 24 and 38 days (1), but the length may vary from cycle to cycle, and may also change over the years.
7. The lining of the uterus, called the endometrium, thickens and then thins over the course of a menstrual cycle and thickens considerably during pregnancy. Embedded in this lining are glands that can secrete a fluid that will help nourish a pregnancy until a placenta is formed.
8. In post-pubertal females, the dominant egg continues to develop, relying on hormones for growth and stimulation. When the egg becomes fully mature, the follicle surrounding the egg bursts, and releases a mature egg which travels through the fallopian tube toward the uterus.
