The volume of air flowing into the alveoli during inhalation/inspiration is increased when there is an increase in which of these?

Question

Quizplus · Accepted Answer

The volume of air flowing into the alveoli during inhalation/inspiration is directly proportional to the pressure gradient from the atmosphere to the alveoli. As the pressure gradient increases, more air flows into the lungs.

Another possible answer:

Answer: E 
 The volume of air flowing into the alveoli during inhalation/inspiration is also influenced by the intrapleural pressure. If the intrapleural pressure is lower than the atmospheric pressure, the lungs will expand and more air will flow in. This is partly determined by the volume of air in the intrapleural space, which can be affected by factors such as changes in lung compliance, chest wall compliance, and intrathoracic pressure. If the intrapleural pressure is too high, it can compress the alveoli and make it harder to breathe.
