cells and structures forming protective and functional tissue layers
Epithelial components refer to the cells and structures that make up the epithelium, which is the tissue forming the outer layer of the body's surfaces and lining the cavities and organs. These components include various types of epithelial cells, such as squamous, cuboidal, and columnar cells, which serve functions like protection, secretion, and absorption. For example, the skin's outer layer and the lining of the gut are made of epithelial components.
