Body Tissues: Transitional Epithelium Quiz

Transitional Epithelium

• Transitional epithelium is a specialized type of stratified epithelium primarily found in the urinary system.
• It lines structures like the bladder, ureters, and part of the urethra, enabling them to stretch and contract.
• This epithelium can change shape, appearing more rounded when relaxed and more flattened when stretched.
• The unique structure allows for the expansion and recoil necessary to accommodate varying volumes of urine.
• Transitional epithelium consists of multiple layers of cells, providing a protective barrier against urine's potentially damaging substances.
• The surface cells, known as umbrella cells, play a vital role in retaining water and maintaining homeostasis within the urinary tract.
• Transitional epithelium is resilient, facilitating continuous exposure to urine without significant cellular damage or loss of function.
