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.
The epithelium is a layer of cells-epithelial cells. They are highly specialised for selective secretion and absorption of ions and molecules. Epithelial cells line any surface that comes into contact with the external environment. So-the airways, the gut, the urinary tract, the cornea etc.tratified squamous epithelium is found in areas where layers of epithelial cells are likely to be sloughed off. Examples of simple squamous epithelium: 1  Endothelium-lines the circulatory system. 2  Mesothelium-lines the peritoneal (abdominal), pleural (lung) and pericardial (heart) cavites.
