LM of a villus in the small intestine
Numéro d’image : 12070830
| Intestinal villus. Light micrograph of a section through a villus in the small intestine. Villi are projections on the intestinal wall adapted for food absorption. At centre,the core of the villus contains blood capillaries. The exterior wall is lined by columnar epithelial cells,each with a nucleus (pink/purple). These cells are specialised for food absorption,assisted by a dark blue "brush border" on their external surface. Food then passes into the bloodstream. Scattered among the epithelial cells are goblet cells (large,dark-staining) which secrete mucous to assist the movement of food through the gut. Toluidine blue stain.
