Histology[edit]

Arrangement consists of several layers of closely packed, flexible and easily stretched cells.

Transitional epithelium in bladder[edit]

When the surfaces of the cells are stretched, as in a full bladder, the cells appear squamous or flat but when the tissue is relaxed, as in an empty bladder, the layers of cells look ragged like the teeth of a saw.

Distribution[edit]

Transitional epithelium lines the pelvis of the kidney, the ureters, the urinary bladder, and the upper part of the urethra.
