The epithelium of the villi is made up of tall columnar absorptive cells called enterocytes, and goblet cells, which secrete mucin, for lubrication of the intestinal contents, and protection of the epithelium. This shows the epithelium of part of a villus at high magnification.his is a diagram which shows the villi of the small intestine, as indicated by the arrows in the diagram above, at higher magnification. The main functions of the small intestine are digestion, absorption of food and production of gastrointestinal hormones. The small intestine is 4-6 metres long in humans.
