Connected to the oral, nasal, laryngeal, and esophageal cavities, the pharynx primarily assists with breathing and swallowing. A common space called the isthmus makes it possible to breathe through the mouth and the nose at the same time. It connects the oral to the nasal pharyngeal areas, where the food and air passageways cross. Inhaled air enters the larynx through the pharynx, then travels through the trachea and into the bronchioles and the alveoli in the lungs. Foods and liquids pass through the pharynx into the esophagus using the process of peristalsis.
