Epiglottis
The structure that closes off the rest of the pharynx when we are eating is called the epiglottis. It is a flap-like structure located just above the larynx. When we swallow, the epiglottis covers the opening of the larynx, directing food and liquids towards the esophagus and preventing them from entering the airway.
The eustachian tubes branch off the pharynx. These allow pressure balance to be maintained behind the eardrums.
When swallowing, the epiglottis closes off the trachea to direct food down the esophagus.
The epiglottis is a flap of tissue that closes off the trachea from the esophagus (or vice versa), so that food being swallowed goes through the esophagus, and air goes to the lungs. While it is still possible to "swallow air" with food, the epiglottis usually prevents any food or drink from reaching the bronchial tubes. When this does happen inadvertently (as when trying to eat and talk at the same time), it triggers a coughing reflex to expel the inhaled material. This can sometimes result in food being forced up into the nasal passages as well. Conversely, failure of the epiglottis to function when regurgitation occurs (throwing up) can allow acidous fluid coming from the stomach to reach the lungs, which is a dangerous medical situation.
