Y1 - 2023 N1 - T2 - Fishman’s Pulmonary Diseases and Disorders, 6e AB - The upper airway is conventionally described as being made up of all the structures that conduct air between the carina and the nares and includes the trachea, larynx, pharynx, nasal airway, and oral airway. Upper airway structures may change their physiologic function in response to pressures around them and anatomic structures near them. Thus, physiologically, the segments of the upper airway behave differently when they are subject to pleural pressures (anatomically intrathoracic) or ambient pressures (anatomically extrathoracic). Furthermore, extrathoracic airway function may change with posture, sleep/wake state, and the function and anatomy of tissues surrounding the airway.
