MICROANATOMY

Detailed explanation-1: -The uterus wall is made up of 3 layers. The inside is a thin layer called the endometrium, which responds to hormones – the shedding of this layer causes menstrual bleeding. The middle layer is a muscular wall. The outside layer of the uterus is a thin layer of cells.

Detailed explanation-2: -Perimetrium: The outermost, protective layer. Myometrium: The highly muscular middle layer. This is what expands during pregnancy and contracts to push your baby out. Endometrium: The inner layer or lining of your uterus (uterine lining).

Detailed explanation-3: -Placenta. An organ shaped like a flat cake. It only grows during pregnancy. The fetus takes in oxygen, nutrients, and other substances from the placenta and gets rid of carbon dioxide and other wastes.

Detailed explanation-4: -Endometrium: the inner lining and consists of the functional (superficial) and basal endometrium. Myometrium: the muscle layer and is composed of smooth muscle cells. Serosa/Perimetrium: the thin outer layer composed of epithelial cells.
