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
