ANATOMY

Detailed explanation-1: -When the urinary bladder fills with urine, the bladder wall stretches to accommodate the increased volume. In the distended bladder, the urothelium reorganizes into two or three layers without any structural damage. Due to this transitional ability of the urothelium, it is also known as the transitional epithelium.

Detailed explanation-2: -Assertion :Urinary bladder and ureters are lined by transitional epithelium.

Detailed explanation-3: -Updated On: 27-06-2022 (b) Urinary bladder and ureters of excretory system are lined by transitional epithelium because it is a stretchable epithelium, hence the urinary bladder and ureters may be considerably stretched without getting torn when they are filled with urine .

Detailed explanation-4: -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-5: -The transitional epithelium of the urinary tract is lined by a layer of glycosaminoglycans (GAGs) that function to prevent microbial and crystal adherence to the bladder epithelium and minimize the movement of urine solutes and proteins through the bladder epithelium.
