In animals, the main protective covering is found in the epithelial tissues. These tissues cover the external surfaces of the body as well as the internal surfaces of organs and body cavities. They protect the body from physical, chemical, and biological damage by providing a barrier between the external environment and the internal tissues and organs. The skin is a good example of the protective function of epithelial tissues, as it prevents the entry of harmful microorganisms, chemicals, and UV radiation. Additionally, epithelial tissues also play a role in absorption, secretion, and sensation.
