3 ways in which carbon dioxide is transported in the blood:
1. DISSOLVED CO2
Carbon dioxide is much more soluble in blood than oxygen
About 5 % of carbon dioxide is transported unchanged, simply dissolved in the plasma
2. BOUND TO HAEMOGLOBIN AND PLASMA PROTEINS
Carbon dioxide combines reversibly with haemoglobin to form carbaminohaemoglobin. Carbon dioxide does not bind to iron, as oxygen does, but to amino groups on the polypeptide chains
