In zootomy, epithelium is a tissue composed of a layer of cells.

Epithelium lines both the outside (skin) and the inside (e.g. intestine) of organisms.

The outermost layer of our skin is composed of dead squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities
