Intestinal lining. Coloured scanning electron micrograph (SEM) of villi (red) from the lining of the duodenum,the first part of the small intestine. Villi are finger-like projections that increase the surface area available for the absorption of nutrients. Cell within the villi produce mucus (grey),a slippery substance that protects the lining and eases the passage of food along the intestines | |
