The liver filters the blood which comes from the digestive tract and transports the filtered blood to the remaining parts of the body. The liver also makes proteins that are used for blood clotting and also albumin an important protein in blood serum which transports fatty acids and steroids. It also absorbs and metabolizes bilirubin.
Bilirubin is formed as the result of the breakdown of hemoglobin, liver stores the iron released by hemoglobin and utilizes it to make the next generation of red blood cells. It also helps in fat metabolization by breaking down fats and making them digest easily. Liver stores carbohydrates which can be broken down into glucose and later used as energy when needed. It also filters blood from waste products, including alcohol and other drugs. Vitamin A, D, E, K, and B12 are stored by the liver.
