• A. Remove metabolic wastes from the blood
• B. Produce digestive enzymes
• C. Regulate blood volume and pressure
• D. Control electrolyte and acid-base balance

Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the primary functions of the urinary system. The urinary system is responsible for filtering blood, removing metabolic wastes, regulating blood volume and pressure, and maintaining electrolyte and acid-base balance.
2. Step 2: Identify the key organs involved in the urinary system, such as the kidneys, ureters, bladder, and urethra, and their roles in performing these functions.
3. Step 3: Compare the listed options to the known functions of the urinary system. For example, removing metabolic wastes, regulating blood volume and pressure, and controlling electrolyte and acid-base balance are all functions of the urinary system.
4. Step 4: Evaluate the option 'Produce digestive enzymes.' Digestive enzymes are produced by organs in the digestive system, such as the pancreas and salivary glands, not the urinary system.
5. Step 5: Conclude that the correct answer is 'Produce digestive enzymes,' as it is not a function of the urinary system.
