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 peritoneum is a membrane made up of two layers. One layer lines the cavity and the other layer lines the organs. The peritoneum helps support the organs in the abdominal cavity and also allows nerves, blood vessels, and lymph vessels to pass through to the organs.
