Why is the second half of a menstrual cycle called seceretory phase in human female? |
|
Answer» During the secretory phase of the uterus, the HORMONE progesterone is PRODUCED by the OVARIES. Progesterone (as well as estrogen) is SECRETED by the corpus luteum, (which means yellow BODY), which develops from the Graafian follicle. Progesterone secreted by the corpus luteum stimulates the further build-up of the cells in the endometrium of the uterus. Progesterone also stimulates the glands in the uterus to secrete substances that maintain the endometrium and keep it from breaking down. For this reason, this phase of the menstrual cycle is called the secretory phase. |
