Small intestine lining. Light micrograph of a cross-section through the healthy lining of a human duodenum, the uppermost part of the small intestine. The lining is folded into numerous villi (round), which project from the intestinal lining, seen here in cross-section. The villi increase the surface area for the digestion of food and the absorption of digestive products. Magnification unknown.
