Which of the following does not stimulate alveolar hyperventilation ?
Correct answer: A. Stretching of airways
- A. Stretching of airways
- B. Hypercapnia
- C. Acidosis
- D. Hypoxia
Explanation
Hypoxia, raised CO2 and acidosis stimulate ventilation through the respiratory control system. Stretching of the airways activates the Hering–Breuer inflation reflex, which inhibits inspiration rather than causing alveolar hyperventilation.
