Which of the following is part of the urinary system?

• A. Lungs
• B. Kidneys
• C. Heart
• D. Stomach

Answer: (B)

The urinary system consists of organs that filter blood and eliminate waste as urine. The kidneys are the key players here: they remove waste products and extra fluids from the bloodstream, regulate water and electrolyte balance, and help maintain the body’s acid-base balance. This is why they’re part of the urinary system. Lungs handle respiration, the heart pumps blood through the circulatory system, and the stomach is part of the digestive system. These functions are separate from urine production, so they aren’t considered part of the urinary system.
