The uterus or womb is an inverted pear-shaped organ with thick muscular walls. It is located within the pelvis, between the bladder and rectum.

The uterus is composed of three layers: the outer peritoneal layer, the middle muscular layer, and the innermost lining, known as the endometrium. The endometrium thickens and prepares for implantation each month during the menstrual cycle, and if pregnancy does not occur, it is shed during menstruation.

On top of that, the muscular walls of the uterus can stretch and expand to accommodate a growing fetus. During labour, the muscular walls contract to push the baby out through the cervix and the vagina.
