Lesson Summary. Transitional epithelium is a layer of cells that form the mucosal lining of your ureters, a portion of your urethra, and your urinary bladder. The cells are stratified, which means they create several layers. These cells provide protection and allow the vessels to expand to accommodate fluid.
In addition to this protective function, epithelial tissue may also be specialized to function in secretion and absorption. Epithelial tissue helps to protect organs from microorganisms, injury, and fluid loss. Functions of epithelial tissue: 1  the cells of the body surface form the outer layer of skin.2  inside the body, epithelial cells form the lining of the mouth & alimentary canal & protect these organs.pithelial tissue helps to protect organs from microorganisms, injury, and fluid loss.
