Villus Diagram

Cryosections of human small intestinal mucosa showing the villi and crypts (of Lieberkuhn). The villi are finger-like projections which increase the surface area of the intestine, improving the efficiency of food absorption. The crypts are tubular invaginations of the epithelium around the villi. Credit@WellcomeImages
