Which of these statements correctly describes the respiratory mechanism of pH control?
A)Respiratory rate and depth decrease as a compensatory measure to combat metabolic acidosis.
B)The respiratory system can compensate completely for uremic acidosis.
C) Metabolic alkalosis inhibits (depresses) the respiratory centre.
D) The respiratory responses to acid-base imbalances represent the first line of defence against changes in pH of body fluids.

Question

Quizplus · Accepted Answer

Metabolic alkalosis leads to a decrease in hydrogen ion concentration, which can depress the respiratory center, reducing ventilation to retain CO2 and increase acidity.
