Intestinal lining. Coloured scanning electron micrograph (SEM) of villi from the lining of the small intestine. Villi are finger-like projections that increase the surface area available for absorption of nutrients. Goblet cells (red) on the villi secrete mucus (purple),a slippery substance that protects the lining and eases the passage of food along the intestines | |
