The endometrium is the innermost glandular layer and functions as a lining for the uterus, preventing adhesions between the opposed walls of the myometrium, thereby maintaining the patency of the uterine cavity. Adenomyosis is the growth of the endometrium into the muscle layer of the uterus (the myometrium). 2  Endometriosis is the growth of endometrial tissue outside the uterus. 3  Endometrial hyperplasia. 4  Endometrial cancer is the most common cancer of the human female genital tract.
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.
