Final answer:
Ventilation is indeed driven by the pressure difference between the outside air and the air inside the lungs, making the statement true.
Step-by-step explanation:
The statement that ventilation is driven by the pressure difference between the outside air and the air inside the lungs is true. Pulmonary ventilation, or breathing, occurs when air flows from an area of higher pressure to an area of lower pressure. Specifically, during inspiration, atmospheric pressure is greater than intra-alveolar pressure, which is greater than intrapleural pressure. Consequently, air flows into the lungs. During expiration, the pressure gradient reverses, allowing air to flow out of the lungs.
