Solution

intrapleural pressure increases bach toward its preinspiration value.

transpulmonary pressure moves back towards its preinspiratioin value, allowing the lungs to passively recoil toward their preinspiration size.

the diaphragm and inspiratory intercostal muscles stop contracting causing lungs to recoil inward.

air flows out of lungs

alveolar pressure becomes greater than atmospheric pressure.

the air in alveolar sacs becomes compressed.
