Answer:
uterus
Explanation:
The uterus, also known as the womb, is the hollow, pear-shaped organ in the female pelvis in which fertilization of an ovary (egg), implantation of the resulting embryo, and development of a baby take place. It is a muscular organ that both stretches exponentially to accommodate a growing fetus and contracts in order to push a baby out during childbirth. The lining of the uterus, the endometrium, is the source of the blood and tissue shed each month during menstruation.
