Question

Quizplus · Accepted Answer

The lungs respond to metabolic acidosis by increasing respiratory rate to decrease carbon dioxide levels and lower the acidity of the blood. This is shown in Figure 27-16, which indicates that increased ventilation leads to a decrease in PaCO2, and therefore a decrease in H+ concentration in the blood.
