The lungs are identified as the main organ of the respiratory system due to their crucial role in gas exchange. They are responsible for inhaling oxygen from the air and exhaling carbon dioxide, a waste product of metabolism. The structure of the lungs, with their extensive surface area created by alveoli, allows for efficient absorption of oxygen into the bloodstream and the removal of carbon dioxide.

The other components of the respiratory system play important but supporting roles. For example, the nose warms, humidifies, and filters incoming air while also housing olfactory receptors, the trachea serves as the airway connecting the throat to the lungs, and the diaphragm is a muscle that aids in the mechanical process of breathing by contracting and relaxing to change the volume of the chest cavity. However, it is the lungs that ultimately facilitate the essential exchange of gases that defines the function of the respiratory system.
