👉 The term "cecum" is a medical term that refers to the female genitalia, specifically the opening at the base of the uterus. The cecum is a muscular sac located near the end of the uterus, and it contains the large intestine (the large bowel) and a small bowel that runs into the colon. In humans, the cecum is lined by mesentery, which is a layer of tissue between the wall of the womb and the uterine lining.
