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.
