Step 1: Function of the urinary bladder.
The urinary bladder is a storage organ for urine. It does not participate in enzymatic activity or secretion. Its primary role is to store urine and expel it during urination.
Step 2: Analysis of options.
Amylase: An enzyme secreted by the salivary glands and pancreas for carbohydrate digestion, not by the urinary bladder.
Urease: An enzyme found in certain bacteria that hydrolyzes urea; not secreted by the urinary bladder.
Renin: An enzyme secreted by the kidneys to regulate blood pressure, not by the urinary bladder.
Urinary bladder: It does not secrete any enzymes; it functions solely as a storage and excretory organ.
