What types of forces resist the movement of air into the lungs?
Which muscles are responsible for moving air into the lungs?
What must the respiratory muscles generate in order to move air into the lungs?
Study Notes
Respiratory System
- Two types of forces resist the movement of air into the lungs:
- Elastic forces of the lungs and chest cage
- Resistive forces of the airways
- The primary muscles responsible for moving air into the lungs are:
- Diaphragm
- External intercostal muscles
- Accessory muscles (such as sternocleidomastoid, scalene, and pectoralis)
- The respiratory muscles must generate negative pressure to move air into the lungs
