In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. Can you relate this fact to the pattern of expiratory and inspiratory flow? Hint: the normal pattern of breathing is efficient in that it requires muscular effort for only a short time.
- In quiet breathing muscular effort is used mainly in inspiration.
- Expiration is largely passive due to elastic recoil of the luna.
- We can relate this fact to the pattern of expiratory and inspiratory flow because in our experiment the expiration rate took longer than the inspiratory rate because expiration was passive and involves returning to the normal state.
