Like our lungs and kidneys, the liver is an organ that we usually don't think about until something goes wrong with it. We take for granted that it will do everything it is supposed to do, like metabolizing and storing carbohydrates and fats, cleaning the bloodstream, regulating blood sugar, helping the body detoxify from drugs and alcohol, and hundreds of other functions. The liver is the only organ that can regenerate itself, making it easier for living donors to donate because once they do, their own livers return to normal size within two months.
