Use this prepared slide to illustrate the morphology of simple columnar epithelium. This type of epithelial tissue consists of a single layer of column-shaped cells. Shown is a tissue section from the human intestine or gallbladder.
Epithelial tissue covers or lines body surfaces as well as serving to absorb, filtrate, protect, and secrete various substances. The tissue is classified by the number of cell layers it has (simple=1 cell layer, stratified=more than 1 cell layer) and the shape of the cells (squamous=flat, cuboidal=cube-shaped, columnar=column-shaped).
Stained with hematoxylin and eosin.
