Detailed explanation-1: -Transitional epithelium: A transitional epithelium (also known as urothelium) is made up of several layers of cells that become flattened when stretched. It lines most of your urinary tract and allows your bladder to expand.

Detailed explanation-2: -To help achieve this, the cells of transitional epithelium are connected by tight junctions, or virtually impenetrable junctions that seal together to the cellular membranes of neighboring cells. This barrier prevents re-absorption of toxic wastes and pathogens by the bloodstream.

Detailed explanation-3: -a) Transitional epithelium, unique compared with other epithelial types is unique because it is specialized for stretching.

Detailed explanation-4: -Functions of epithelial tissue are secretion, protection, absorption, transportation and special sensory receptive.

Detailed explanation-5: -Transitional epithelium is a stratified tissue made of multiple cell layers, where the cells constituting the tissue can change shape depending on the distention in the organ. When the organ is filled with fluid, cells on the topmost layer of this epithelium can stretch and appear flattened.
