Accepted Answer

Excess iron is stored in the form of hemosiderin and ferritin in the liver and spleen. Transferrin is a protein that transports iron in the blood. Urobilin and stercobilin are breakdown products of hemoglobin and are responsible for the color of urine and feces. Bilirubin and biliverdin are also breakdown products of hemoglobin and are excreted in bile.
