Overview
Plica circulares are clearly shown in this longitudinal section of the jejunum. Plica circulares provide increased absorptive surface area for the intestine. They consist of circular folds comprised of a central core of submucosa covered by the mucosa with its villi and glands. The mucosa also contains collections of lymphoid tissues, referred to as mucosa-associated lymphoid tissue (MALT). Jejunum, 40x
