If red blood cells carry oxygen, do they also carry carbon dioxide?

To some degree: • While O2 is transported via the Hgb of the RBC, carbon dioxide is more soluble in blood than oxygen. About 5 % of carbon dioxide is transported unchanged, simply dissolved in the plasma. Carbon dioxide additionally does combines reversibly with haemoglobin to form carbamino haemoglobin. About 10 % of carbon dioxide is transported bound to haemoglobin and plasma proteins.
