Normally, much more oxygen is transported in combination with hemoglobin than physically dissolved in the blood. Without hemoglobin, the cardiovascular system could not transport sufficient oxygen to meet tissue demands. The blood carries carbon dioxide in physical solution, chemically combined to amino acids in blood proteins, and as bicarbonate ions.
