The Urinary Bladder Is Composed Of Transitional Epithelium

The urinary bladder is a muscular organ found in the lower abdomen. It stores urine until it is ready to be excreted. The wall of the bladder is made up of several layers, including the urothelium or transitional epithelium. This type of epithelium is found in several organs, including the bladder, ureters, and urethra.

The urothelium of the bladder is composed of two layers: an upper, non-keratinized squamous epithelium and a lower, cuboidal epithelium. The upper layer is responsible for protecting the contents of the bladder from the external environment, while the lower layer creates a mucosal surface that is impermeable to most materials. The transitional epithelium is also able to stretch and expand as the bladder fills.

The bladder wall also contains several other components that work together to maintain the bladder’s function. These include the muscle layer, which is responsible for the contraction and relaxation of the bladder, and the lamina propria, which provides support to the bladder wall. In addition, there is a submucosa layer, which helps maintain the shape of the bladder, and provides a moist surface for urine to flow through. Additionally, the rugae of the bladder are folds of the mucosa that allow the bladder to expand when it fills.

The transitional epithelium of the bladder is important for its normal functioning. In some cases, these cells can become malignant, leading to urinary bladder cancer. Treatment of this type of cancer typically involves a combination of surgery, radiation, and chemotherapy.
