Text Solution
Verified by ExpertsThe correct answer is:
A
Chloride shift is the movement of chloride ions from the plasma into red blood cells as a result of the transfer of carbon dioxide from tissues to the plasma, a process that serves to maintain blood ph. Bicarbonate and chloride ions are transported across the RBCs membrane in opposite directions by the bicarbonate chloride carries proteins. Thus, removal of 
from blood involves influx of 
into RBCs.
