The urinary system does all of the following, except that it:

• A. helps control electrolyte balance
• B. produces digestive enzymes
• C. regulates blood volume and pressure
• D. removes metabolic wastes from the blood

Answer: (B)

Verified step by step guidance

1. Step 1: Begin by identifying the primary functions of the urinary system. The urinary system is responsible for filtering blood, removing waste products, regulating electrolyte balance, maintaining fluid balance, and controlling blood pressure.
2. Step 2: Understand that the urinary system does not produce digestive enzymes. Digestive enzymes are produced by organs in the digestive system, such as the pancreas, salivary glands, and stomach.
3. Step 3: Compare the listed functions in the problem with the known functions of the urinary system. Functions such as regulating blood volume and pressure, removing metabolic wastes, and controlling electrolyte balance are all roles of the urinary system.
4. Step 4: Eliminate the option that does not align with the urinary system's functions. Since producing digestive enzymes is not a function of the urinary system, this is the correct answer.
5. Step 5: Conclude that the urinary system does not produce digestive enzymes, as this is a function of the digestive system, not the urinary system.
