One of the most important functions of the liver is to filter the blood that runs through the body. When harmful substances such as drugs, alcohol, metabolic waste and chemicals are ingested and reach the liver, they are at least partially filtered out before the rest of that material hits the blood stream. Healthy livers can usually filter about 1.5 quarts of blood per minute, or about 540 gallons of blood per day. | One of the most important functions of the liver is to filter the blood that runs through the body.
