The respiratory zone is the region of the respiratory system where gas exchange (oxygen and carbon dioxide) occurs. It includes the bronchioles, alveolar ducts, and alveoli, all of which are responsible for the exchange of gases between the air and blood. The trachea, nose, and nasal cavity are part of the conducting zone, which transports air to and from the respiratory zone.
