bicarbonate

In blood CO₂ is transported in three different states:-

In dissolved state- 7% of CO₂ gets dissolved in the blood plasma and is carried in solution to lungs or about 0.3 mL of CO₂ is transported per 100 - mL of blood in dissolved state in blood plasma.
In the form of bicarbonate- About 70% of CO₂(about 2.5 mL per 100 mL of blood), received by blood from tissues, enters the RBCs where it reacts with water to form carbonic acid (H₂CO₃).
As carbaminohaemoglobin- About 23% of CO₂ is transported in combination with haemogloblin and plasma proteins. CO, reacts directly with amine radicals (NH₂) of haemoglobin to form an unstable compound carbamino-haemogloblin (Hb. CO₅) Sodium bicarbonate act as buffer of blood.
