1.1 Structure of the respiratory system
Pulmonary ventilation, the movement of air into and out of the lungs, involves the main structures of the respiratory system (Figure 1). They include:
- the lungs
- a system of airways that deliver the air to the blood vessels of the lungs
- the musculoskeletal system that ventilates the lungs
- the central and peripheral nervous system that controls the rate and depth of breathing.
