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 breaks down fats. Additionally, the liver processes nutrients absorbed from the intestines and converts them into energy or stores them for later use. Another important role of the liver is detoxification. It filters harmful substances from the blood, including drugs and alcohol, and helps to eliminate waste products. The liver also regulates blood sugar levels and produces proteins necessary for blood clotting and other bodily functions.
