Haemoglobin is a protein used by all vertebrates and some invertebrates for oxygen transport. In vertebrates it occurs in red blood cells (erythrocytes), giving them their colour. In the lungs or gills where the concentration of oxygen is high, oxygen attaches to haemoglobin to form oxyhaemoglobin. This process effectively increases the amount of oxygen that can be carried in the bloodstream. The oxygen is later released in the body tissues where it is at a low concentration, and the deoxygenated blood returned to the lungs or gills. Haemoglobin will combine also with carbon monoxide to form carboxyhaemoglobin, but in this case the reaction is irreversible. Research Haemoglobin
