Transport of Gases Presents to you by ABOUT DISEASE.CO TEAM
Transport of CO 2 Dissolved in plasma As bicarbonate ions As carbamino Hb or Carbamino Proteins
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
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
Transport as carbamino Hb Accounts for 23% of CO2 transport from cells to lungs CO2 + Hgb HgbCO2 Or CO2 +Plasma Proteins P.PCO2
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.
