Answer:
False
Step-by-step explanation
When air flows into the lungs, the process is known as inspiration. During inspiration, expansion of the lungs occurs due to the contraction of external intercostal muscles and the relaxation of internal ones. Expansion of the lungs allows the increase of alveolar volume due to which alveolar pressure decreases. When alveolar pressure becomes significantly lower than the atmospheric pressure, air flows into the lungs, to balance the air pressure.
Alveolar pressure becomes equal to atmospheric pressure only at the end of expiration. As air pressure remains equal on both sides, no movement of air occurs.
