What prevents us from choking on food?

The body has several mechanisms to prevent choking on food, primarily the coordinated actions of swallowing and the gag reflex. When we swallow, the epiglottis closes over the trachea to direct food into the esophagus, while the muscles in the throat contract in a synchronized manner to push the food down. Additionally, the gag reflex can help expel any object that accidentally enters the airway. These protective reflexes are crucial for ensuring safe swallowing and maintaining an open airway.
