The liver removes poisons, and blood with newly digestive food is sent through the liver for detoxification. The liver stores glycogen, picking up excess blood sugar, and breaking down the glycogen when blood sugar is low. The liver synthesizes blood proteins, such as albumins and the proteins that carry cholesterol.
