Hemoglobin dramatically increase the oxygen carrying capacity of blood, serving to transport large volumes of oxygen from respiratory organs to metabolically active tissues, which allows for the maintenance of the high metabolic rate enjoyed by vertebrate animals. Test your basic knowledge of hemoglobin by taking this simple quiz.
