None occurance as the blood passes through systemic capillaries

Which of the following does not occur as the blood passes through systemic capillaries?

A. Increased protein content 
B. Shift of Hemoglobin dissociation curve to left
C. Increased hematocrit 
D. Decreased pH

Ans. B

    In systemic capillaries, O2 is released (i.e., O2 dissociation curve shifted to right) and CO2 is acquired (CO2 dissociation curve shifted to left). In systemic capillaries, there is decrease in Ph and increase in hematocrit, protein content, H+, Cl- & HCO3- ion concentration.
