Which organ is part of the urinary system?

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

Answer: (D)

The urinary system consists of organs that filter wastes from the blood and maintain fluid and electrolyte balance. The kidneys are the central organs here; they filter blood, remove wastes and excess water, adjust mineral levels, and produce urine. Urine then travels from the kidneys through the ureters to the bladder and is excreted via the urethra. The heart belongs to the circulatory system, the liver to the digestive/metabolic system, and the lungs to the respiratory system. Because of these roles, kidneys are the organ that fits the urinary system.
