This can occur in the mouth or nose, in the throat, in the larynx (voice box), in the trachea (breathing tube), or further down into the lungs. It is created by turbulent, or irregular, airflow caused by the narrowed airway. WebbThe membranes in the bronchial tubes can thicken, and the layer of smooth muscle surrounding them increases.
