Which structures are part of the upper airway?

The upper airway consists of the structures that bring air into the body and begin conditioning it before it moves deeper: the nose and mouth for entry, and the pharynx and larynx as the passages that carry air down toward the lungs. The nose and mouth filter, warm, and humidify the air; the pharynx and larynx act as conduits that also help protect the lower airway from aspiration. The trachea sits below this region, making it part of the lower airway, while the lungs are the sites of gas exchange and the diaphragm is a breathing muscle, not part of the airway itself.
