Small intestine lining. Light micrograph of a section through the lining (mucosa) of the small intestine. It shows crypts of Lieberkuhn (purple folds,lower) between the intestinal villi (projections,upper). The crypts produce new cells by constant cell division; these progress up the villi to renew the intestinal lining. The lining of the villi and crypts is composed of columnar enterocyte cells,which are involved in digestion and absorption,and mucus-secreting goblet cells (blue). At the base of the crypts are Paneth cells (stained red),which are thought to protect the intestine from disease. At bottom is a muscle layer (blue). Magnification unknown | |
