EpithelialTissue
Epithelium is one of the four basic types of animal Tissue, along with ConnectiveTissue, MuscleTissue and NervousTissue. It is a thin, continuous, protective layer of cells. Epithelial tissues line the outer surfaces of organs and BloodVessels throughout the body, as well as the inner surfaces of cavities in many internal Organs. An example is the epidermis, the outermost layer of the Skin. [from Wikipedia]
