ANS: 3
The respiratory system tries to correct metabolic acidosis by increasing ventilation to reduce the amount of carbon dioxide and thereby raise the pH. The respiratory system would compensate for metabolic acidosis with increased respirations, not hypoventilation. Bicarbonate is the renal component of acid-base balance, not the respiratory component. The pH measures hydrogen ion concentration. Alternating deep versus shallow breaths is not a compensating mechanism of the respiratory system for metabolic acidosis. The respiratory system does not compensate by ex-panding the lung tissues to their fullest. In metabolic acidosis, the respiratory system compensates by exhaling a greater amount of carbon dioxide.
