2. Transport of CO 2  Dissolved in plasma  As bicarbonate ions  As carbamino Hb or Carbamino Proteins

3. Transport of CO2 in Dissolved state Accounts for 7% of all the CO 2 normally transported  At PCO2 of venous blood 2.7 ml/dl  At PCO2 of arterial blood 2.4 ml/dl i.e. 0.3 ml of CO 2 is transported in the form of dissolved CO 2 by each dl of blood

4. Transport as bicarbonate ions Accounts for 70% of CO2 transport from cells/ tissues to lungs. CO2 + H2O H2 CO3 H + HCO3 H +Hgb HHgb Cl Cl Plasma

5. Transport as carbamino Hb Accounts for 23% of CO2 transport from cells to lungs CO2 + Hgb HgbCO2 Or CO2 +Plasma Proteins P.PCO2

8. Haldane Effect Binding of oxygen with hemoglobin tends to displace carbon dioxide from the blood or deoxy Hb is more active in combining with carbon dioxide than oxy Hb.
