[en] The main airway function is the conduction of thé air from the amblent air to the gas exchange regions of the lung and conversely. Upper airway include nasal cavities, pharynx, larynx and extrathoracic trachea. These structures, supported by bones, cartilages or muscles, must be as permeable as possible to the air. flow. If for structural or functional reasons, a permanent or dynamic narrowing occurs along the airway, the resulting bottleneck will increase the resistance to airflow, thus impair ventilation and generate abnormal respiratory noises, and finally decrease the exercise capacity. This paper focuses on the function and potential dysfunctions of the different parts of the upper airway in horses
