The epithelial tissue is designed to secrete lubricants, regulate temperature, and safeguard the body from the harmful substances. These tissues line the outer surface of the organs and the blood vessels all through the body and on the inner surface of the cavities.
The epidermis is an example of epithelial tissue. Some of the major activities of epithelial tissue comprise transcellular transport, selective absorption, secretion, and sensing.
