Intestinal villi. Coloured scanning electron micrograph (SEM) of a section through a part of the small intestine, showing the villi that cover its inner surface. Villi are finger-like projections that line the surface of the small intestine and increase the surface area available for the absorption of nutrients from digested food. Magnification: x35 when printed 10 centimetres wide.
