MICROANATOMY

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

Detailed explanation-2: -Answer and Explanation: The bladder is lined with transitional epithelial cells because the properties of a transitional epithelium allow the bladder to expand as it fills without damaging the bladder lining.

Detailed explanation-3: -The inner mucosa is lined with transitional epithelium and scattered goblet cells that secrete protective mucus. The muscular layer of the ureter consists of longitudinal and circular smooth muscles that create the peristaltic contractions to move the urine into the bladder without the aid of gravity.
