The lower abdomen mainly includes the small intestine, colon, cecum, rectum, anus, bladder, prostate (male), uterus (female), and ovaries (female). The small intestine is divided into three parts: duodenum, jejunum, and ileum, which are the main places for digestion and absorption of dietary items. The large intestine includes four parts: colon, cecum, rectum and anus, and is the main place for absorbing water and forming feces. The bladder is the urinary storage organ, located in the pelvis, which receives and stores urine. The uterus is the place where the female nurtures the fetus. The ovary is the female reproductive organ that produces and expels egg cells that unite with sperm to become a fertilized egg that lays in the uterus.
