| diverticula | The plural of diverticulum. As a person ages, pressure within the large intestine (colon) causes pockets of tissue (sacs) that push out from the colon walls. A small bulging sac pushing outward from the colon wall is a diverticulum. Diverticula can occur throughout the colon but are most common near the end of the left side of the colon, the sigmoid colon. (12 Dec 1998) |
