Final answer:
The uterus is composed of three tissue layers: the endometrium, myometrium, and perimetrium, each playing a distinct role in reproductive health and function.
Step-by-step explanation:
The three layers of tissue within the uterus are the endometrium, myometrium, and perimetrium.
- The endometrium is the innermost layer, consisting of epithelial tissue and a connective tissue lining called the lamina propria. It has two sub-layers: the stratum basalis, which does not shed during menstruation and the stratum functionalis, which grows and sheds in response to hormonal changes during the menstrual cycle.
- The myometrium is the middle layer comprised of a thick layer of smooth muscle that enables powerful contractions during labor, as well as the less intense contractions experienced during menstruation.
- The perimetrium is the outermost layer, which is a serous membrane that covers the exterior of the uterus and allows for movements without friction against other pelvic organs.
