WebThe architecture of the lining of the small and large intestines is unique, with extensive folding of the epithelial cells to form crypts and fingerlike projections called villi.111 Such an arrangement increases the overall surface area of the intestinal lumen to permit maximal interaction of ingested nutrients with the epithelial cells for … WebMar 29, 2024 · Functions of Microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions. In the intestine, they work in conjunction with villi to absorb more nutrients and more material because they expand the surface area of the intestine. The microvillar membrane is …

WebThe mucosa of the small intestine has some adaptations to the functions it serves. It is heavily creased into the structures that increase the surface area where the nutrients are digested and absorbed. These adaptations include intestinal folds called the plicae circulares, villi, and microvilli. WebThe luminal surface of the enterocytes have microvilli (1 micrometer long) while the cell layer itself is folded to form villi (0.5-1.6 millimeters long) and crypts. Both serve to increase the total absorption surface of the intestine. fisheries ppt presentation
