Besides its digestive functions, the liver stores vitamins and minerals, synthesizes proteins, breaks down waste products, and regulates blood clotting.
Step-by-step explanation:
The liver is an organ that plays a vital role in digestion and metabolism. Besides its digestive functions, the liver also has additional roles such as storing vitamins and minerals, synthesizing proteins, breaking down waste products and toxic substances, and regulating blood clotting. For example, it stores vitamins A, D, B12, and K, synthesizes proteins like fibrinogen and albumen, and breaks down waste products that are excreted in bile or urine.
