transitional epithelium
Quick Summary
Transitional epithelium is a type of tissue found in the urinary tract, most notably the urinary bladder. It is characterized by multiple layers of cells that can change shape. When the bladder is empty or contracted, these cells appear more rounded or dome-shaped. However, when the bladder is stretched, as when it fills with urine, the cells flatten out, allowing the organ to expand. This unique ability to change shape is crucial for the function of organs like the bladder, which need to accommodate varying volumes.12
