Clinical Correlates of pH Levels
Problem Set

Problem 3: Rapid response to mild acidosis

The bicarbonate buffering system of blood can respond quickly to mild metabolic acidosis (between pH 7.15 and 7.35) by:

A. expelling CO2 in the lung.
B. retaining HCO3- in the kidney.
C. excreting H+ in the kidney.
D. direct buffering action of the H2CO3 central intermediate.
E. retaining CO2 in the lung.
