Final answer:
The three layers of the uterus wall are the endometrium, myometrium, and perimetrium, each serving different functions related to menstruation, pregnancy, and protection.
Step-by-step explanation:
The three layers of the uterus wall are the endometrium, myometrium, and perimetrium. The innermost layer, the endometrium, contains the stratum basalis and stratum functionalis, which are part of the lamina propria. The endometrium is critical for implantation and changes during the menstrual cycle. The middle layer is the myometrium, which is a thick layer of smooth muscle that facilitates uterine contractions during labor and menstruation. The outermost layer is the perimetrium, a serous membrane that covers the exterior of the uterus and provides lubrication to prevent friction with other pelvic organs.
