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.
  Epithelium is found covering external or internal surfaces in the body.   Stratified epithelium consists of more than one layer of cells. It is often found in situati â¦ ons subject to abrasion, where the top layers of cells are worn off.Layers underneath replace the lost cells, so the basic function of stratified epithelium is protection.
