The womb, also known as the uterus, is a vital organ in the female reproductive system. It is where a fertilized egg implants and develops into a fetus during pregnancy. The womb has a muscular structure that can expand to accommodate a growing baby and contracts during childbirth to help deliver the baby. In addition to its role in reproduction, the womb also plays a part in the menstrual cycle. Each month, it prepares for a potential pregnancy by thickening its lining. If pregnancy does not occur, this lining is shed during menstruation, highlighting the womb's cyclical function in women's health.
