The largest organ of the digestive system is the liver. Weighing about three pounds and performing over 500 essential functions, the liver plays a crucial role in digestion, metabolism, and detoxification. It produces bile, which helps emulsify fats in the small intestine, making them easier to digest. The liver also regulates blood sugar levels, stores vitamins and minerals, and metabolizes drugs and alcohol. In addition, it synthesizes proteins important for blood clotting and immune function. Maintaining liver health is vital for overall well-being, and lifestyle factors such as diet, exercise, and alcohol consumption significantly affect liver function.
