The uterus is about the size of a pear, approximately 3 inches long. A muscular organ, the uterus collapses when empty. Its inner cavity is lined by a tissue called the endometrium, which develops and sheds regularly as part of the menstrual cycle. Menstruation occurs in response to ovarian hormones. The uterus is where the baby develops, and one look at a very pregnant woman tells you that the uterus has the ability to stretch incredibly. Luckily for us women, the uterus also goes back to its regular size after the baby has gone out into the big, wide world — or we’d be big and wide forever.
