The endometrium is the lining layer of the uterus, and functions to prevent adhesions within the opposed walls of the myometrium, thereby maintaining the patency of the uterine cavity.
The endometrium is the inner layer. During a woman's menstrual cycle, hormones cause the endometrium to change. Estrogen causes the endometrium to thicken so that it could nourish an embryo if pregnancy occurs.
