Cat colon. Light micrograph of a section through the colon, part of the large intestine, of a cat. The lumen (white) of the colon is at centre. It is lined with with villi, small projections that greatly increase the colon's surface area. Goblet cells within the villi secrete mucous, which aids the movement of faeces, while absorptive columnar epithelial cells absorb water from the faeces. Two layers of smooth muscle (red) contract and relax to push faeces along the intestine. Magnification: x2 when printed at 10 centimetres wide.
