Question
Which of the following statements are true / false
A. The blood transports CO2 comparatively easily because of its higher solubilityB. Approximately 89% of CO2 is transported being dissolved in the plasma of bloodC. The carbon dioxide produced by the tissues, diffuses passively into the blood stream and passes into red blood corpuscles and react with water to form H2CO3.D. The oxyhaemoglobin (HbO2) of the erythrocytes is basic. E. The chloride ions diffuse from plasma into the erythrocytes to maintain ionic balance.

Solution
The correct option is B A, C and E are true, B and D are false.
The correct option is A.(A) (B) (C)Approximately 75% of carbon dioxide is transport in the red blood cell and 25% in the plasma. The relatively small amount in plasma is attributable to a lack of carbonic anhydrase in plasma so association with water is slow; plasma plays little role in buffering and com- bination with plasma proteins is poor.(E)Chloride shift is a process that occurs in a cardiovascular system, It is the exchange of bicarbonate (HCO3−) and chloride (Cl−) ions across the membrane of red blood cells. In this, the chloride ions shift from plasma to RBCs and bicarbonate ions shifts from RBCs to plasma to maintain the ionic balance.
