What it means
The outer layer of the skin, the lining of the gut and airways and the lining of blood vessels are all epithelium. It protects, absorbs and releases substances. In wound healing, epithelial cells grow in from the edges to cover the wound (epithelialization). Cancers of epithelium are called carcinomas.
