The uterus (Latin word for womb) is a major female hormone-responsive reproductive sex organ of most mammals, including humans. It is within the uterus that the foetus develops during gestation. The term uterus is used consistently within the medical and related professions; the Germanic term, womb is more common in everyday usage. The plural of uterus is uteruses or uteri.
One end, the cervix, opens into the vagina; the other is connected on both sides to the Fallopian tubes.
