hello Daisy.....the answer is as.....

the haemoglobin which is the oxygen carrier containing haem group and iron complex at centre show affinity toward the CO2 molecules........but when the blood moves towards the lungs at alveoli region.......the Oxygen gradient i.e. difference in the concentration of oxygen as well as CO2 takes place.......this makes a direct diffusion of CO2 molecules from blood to alveoli space......and also of oxygen from alveoli space towards blood.........so this is all about the difference in concentration of relative gases........the iron complex makes an anion attractive site to attract O2 molecules toward itself but remember that O2 is always dissolved in blood plasma and not in haemoglobin ... it just turns the blood in red in colour

Answer:

Hemoglobin with bound carbon dioxide and hydrogen ions is carried in the blood back to the lungs, where it releases the hydrogen ions and carbon dioxide and rebinds oxygen. Thus, hemoglobin helps to transport hydrogen ions and carbon dioxide in addition to transporting oxygen.
