What is "uterus"?

The uterus, also known as the womb, is a hollow, muscular organ located in the female pelvis. It serves as the site for the development and nourishment of a fertilized egg during pregnancy. The uterus consists of three layers: the innermost lining called the endometrium, which thickens and sheds during the menstrual cycle; the muscular middle layer known as the myometrium, responsible for contracting during labor and childbirth; and the outer layer called the perimetrium. The uterus is capable of expanding to accommodate a growing fetus and contracts to facilitate the delivery of the baby during childbirth.
