At the end of normal expiration when outward air flow has ceased:
Select one:
O a. Intra-pleural pressure is greater than intra-alveolar pressure
O b. Intra-pleural pressure is greater than atmospheric pressure
O c. Intra-alveolar pressure is equal to atmospheric pressure
O d. Intra-alveolar pressure is less that atmospheric pressure
Intra-alveolar pressure is greater than atmospheric pressure
