WebThe individual epithelial cells also have finger-like projections known as microvilli. The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface. WebMay 20, 2024 · A continuous, postmitotic single layer of intestinal epithelial cells (mostly enterocytes) covers villi and increases the absorptive surface another 600 times due to the presence of microvilli on each cell ( Kiela and Ghishan, 2016 ). Crypts are facing away from the intestinal lumen and sit in invaginations of the intestinal mucosa.
