Work Step by Step
The pharynx serves as the passageway for the air we inhaled and the food and liquid we intake. In the digestive system, the pharynx serves as a passageway for the movement of food and liquid from our mouth to the esophagus. The pharynx pushes the food through muscle contractions. It helps keep the food from entering the windpipe. in the respiratory system, it allows the movement of air from the nose and mouth to the respiratory tract. When air enters the laryngopharynx, the epiglottis diverts it to the larynx. The epiglottis switches the access between the esophagus and trachea, ensuring that the air will enter the trachea while food and liquid are diverted to the esophagus.
