Transport of CO2 CO2 content in the arterial blood = 48ml/dl in Physical solution (3ml/dl) In plasma and RBCs in Chemical Combination (45ml/dl) Tidal CO2: During normal resting condition, an average of 4 ml of CO2 is transported from the tissues to the lungs in each 100 ml of blood....
Transport of CO2 CO2 content in the arterial blood = 48ml/dl in Physical solution (3ml/dl) In plasma and RBCs in Chemical Combination (45ml/dl) Tidal CO2: During normal resting condition, an average of 4 ml of CO2 is transported from the tissues to the lungs in each 100 ml of blood. CO2 dissociation Curve It shows the relationship between the total CO2 content of blood and CO2 tension (PCO2) At the lung: ✓ PCO2 = 40mmHg → CO2 content = 48ml/dl. At the tissues: ✓ PCO2 = 46mmHg → CO2 content = 52ml/dl. Haldane Effect: Binding of oxygen to haemoglobin in the lungs displaces/releases CO2 from the blood to the alveoli. Bohr Effect: Increased CO2 and H+ shift the oxygen dissociation curve to the right, facilitating oxygen release to tissues. Q-Which is more important, Haldane or Bohr effect?? A- Haldane effect
