Inspiration Diaphragm and external intercostals contract Thorax expands Pleural pressure becomes more negative Lungs expand Alveolar pressure becomes sub-atmospheric Air flows into alveoli

Expiration Diaphragm and external intercostals stop contracting Chest wall moves inward Pleural pressure back towards pre-inspiration Lungs recoil towards pre-inspiration size Air in alveoli becomes compressed P alv greater than P atm Air flows out of lungs
