The liver plays a crucial role in metabolism and detoxification by processing nutrients absorbed from food and producing bile to aid digestion. It converts carbohydrates into glucose to regulate blood sugar levels, synthesizes proteins for blood clotting, and stores essential vitamins and minerals. In detoxification, the liver filters toxins and waste products from the bloodstream, converting them into less harmful substances that can be excreted. Maintaining liver health is vital for effective metabolic processes and overall physiological balance.
