The uterine cycle describes a series of changes that occur to the lining of the uterus, or, endometrium, during a typical menstrual cycle. Learning Objective. Key Points. The uterine cycle includes the increase in the endometrium in preparation for implantation, and the shedding of the lining following lack of implantation, termed menstruation.
During the menstrual CYCLE (not the menstrual period), the lining of the uterus, the endometrium, grows blood vessels and blood flows though the vessels.The endometrium and the associated blood vessels and blood is what is shed during the menstrual period. The endometrium also acts like a foreign object to the uterus.Should the egg be fertilized and implant, then the endometrium cannot be shed as if it were, the egg would be flushed out, too.est Answer: Interestingly, it is not the presence of a hormone that causes the endometrium (uterine lining that grows the blood vessels) to be shed, but it is the LACK of a hormone, progesterone, that causes the event.
