Liver cells. Light micrograph of human liver cells (blue) with red blood cells (red). The liver cells are larger, with nuclei (pink). The liver has many functions, including destroying old red blood cells, producing bile for the digestion of fat in the digestive system, breaking down harmful waste products in the blood, and converting some of the blood chemicals into stored food (glycogen) and proteins. Blood arrives by the hepatic artery and the portal vein, and is removed to the heart by the inferior vena cava. The liver is among the largest organs of the body.
