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
