The intestinal epithelium is the cell tissue that lines the large and small intestine. It serves primarily to take part in the digestive process, but it also takes part in the function of the immune system.The epithelium of the intestine is simple columnar, and is nonciliated.Epithelium is a tissue that is made up of a variety of types of cells. It covers the surface of the body and organs, as well as forming the inner lining of body cavities and hollow organs.he epithelium of the intestine is simple columnar, and is nonciliated.

Cells. You need to be able to use your knowledge of the structure of cells and the function of the organelles to interpret electronmicrographs of cells. In particular the epithelial cells lining the small intestine. These are cells which are specialised for absorbing the products of digestion. They will therefore have a large surface area provided by the microvilli and due to the need for active transport across their cell membranes they will contain a large number of mitochondria providing them with ATP. Epithelial cells also secrete enzymes and other proteins.
