Which Correctly Describes the Cause of the Increase in Alveolar

Multiple Choice

Which correctly describes the cause of the increase in alveolar ventilation that occurs when a person ascends to high altitude?

A) The decrease in P_CO2 of inspired air decreases alveolar P_CO2, stimulating the peripheral chemoreceptors.
B) The decrease in P_CO2 of inspired air decreases alveolar P_CO2, stimulating the central chemoreceptors.
C) The decrease in P_O2 of inspired air decreases alveolar and arterial P_O2, stimulating the peripheral chemoreceptors.
D) The decrease in total atmospheric pressure causes a greater negative pressure in the intrapleural space, resulting in deeper and more frequent breathing.
E) The decrease in the total barometric pressure at high altitude causes hypocapnea, which stimulates peripheral chemoreceptors.
