What is the function of the human liver?

The human liver performs a wide variety of vital functions, including detoxifying harmful substances, producing bile for digestion, storing nutrients, and metabolizing drugs and alcohol. It also regulates blood clotting, maintains cholesterol levels, and helps process carbohydrates and fats. The liver filters blood coming from the digestive tract, breaking down toxins like ammonia and converting them into harmless substances. Additionally, the liver stores glycogen, a form of glucose that provides energy between meals, and produces proteins essential for blood circulation.
