What happens to the larynx during swallowing?

During swallowing, the larynx plays a crucial role in protecting the airway from food and liquids. When swallowing occurs, the larynx rises and moves upward and forward in a coordinated action. This movement helps close off the trachea to prevent aspiration, which is when food or liquid accidentally enters the airway. The larynx effectively acts like a lid, sealing off the trachea to ensure that the ingested material goes down the esophagus instead. This is an essential protective mechanism to ensure that the airway remains clear during the swallowing process.

Understanding this function highlights the larynx's dual role in both facilitating breathing during normal respiration and protecting the airway during swallowing. The other options do not accurately reflect what occurs during swallowing. For instance, the larynx does not remain open or closed in a conventional manner concerning airflow—it has a specific function to fulfill during this vital process.
