Which organ removes wastes from the blood?

Explanation:
Removing wastes from the blood is the kidneys’ main job. They filter blood in tiny functional units called nephrons, where waste products like urea, excess salts, and water are removed to form urine. This filtration helps regulate fluid balance, electrolyte levels, and blood pH, keeping the internal environment stable. The liver detoxifies chemicals and metabolizes substances, but it doesn’t directly remove wastes from the bloodstream in the same way. The heart pumps blood around the body, and the lungs expel carbon dioxide and some water vapor, but neither eliminates the wide range of dissolved wastes that the kidneys handle. So, the organ that removes wastes from the blood is the kidney.
