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.
Given the wide distribution, epithelial cells perform a variety of functions: protection (skin), absorption (intestine), secretion (glands), excretion (kidney), gas exchange (lung and blood vessels). To perform these functions, epithelia assemble into different structures. List the junctional complexes that hold epithelial cells together and their primary functions. 2  List the functions of the basement membrane and how epithelial cells attach to the basement membrane.
