Which human organ is primarily responsible for filtering metabolic wastes from the blood and forming urine?

💡 Solution & Explanation

The kidneys are paired bean-shaped organs that filter waste products, excess ions, and water from the blood to produce urine, maintaining systemic osmoregulation. The liver processes nutrients and detoxifies metabolic byproducts, while the heart pumps blood and lungs facilitate gas exchange. Nephrons serve as the functional structural units inside each kidney.
