It is designed to protect the distal airway from ingested material and saliva and to regulate airflow into and out of the airway. e. air continues to move into the lungs until intrapulmonary pressure equals atmospheric pressure protects the superior opening of the larynx FREE COVID TEST can i take advil before a fasting blood test Book Appointment Now. It is commonly referred to as the voice box or the organ of phonation as it houses the structure responsible for sound production. This results in air following the pressure gradient and passively filling the lungs at rest. pg.
