The liver is a vital organ that performs numerous essential functions in the body. It helps in the digestion of food by producing bile, which aids in breaking down fats. Additionally, the liver processes nutrients absorbed from the intestines and converts them into energy or stores them for later use. Another important function of the liver is detoxification. It filters harmful substances from the blood, including drugs and alcohol, and breaks them down into less harmful compounds. The liver also plays a role in regulating blood sugar levels and producing proteins necessary for blood clotting and immune function.
