Final answer:
The tissue described is transitional epithelium, which isfound in the walls of the urinary bladder. When the bladder is relaxed, the cells appear cubelike. When the bladder is distended, the cells transition to a flat or squamous appearance.
Step-by-step explanation:
The tissue described in the question is called transitional epithelium. It is typically found in body areas subjected to stress and tension changes, such as the walls of the urinary bladder. When the bladder is relaxed, the cells of the transitional epithelium appear cubelike. However, when the bladder is distended by fluid, such as urine, the cells transition to a flat or squamous appearance.
