Intestinal blood vessels. Coloured scanning electron micrograph (SEM) of a resin cast of blood vessels from the intestine. This network of vessels infiltrates the tissue,supplying it with blood. The inner wall of the intestines contains folds,called villi,that greatly increase the surface area for the absorption of nutrients and water. The cast was made by injecting resin into the blood vessels and then chemically digesting the surrounding tissues | |
