All of the answers are correct. During deglutition (swallowing), the soft palate elevates to close off the nasopharynx, preventing food or liquid from entering the nasal cavity. The larynx elevates to close off the trachea and the epiglottis covers the opening of the larynx to prevent food or liquid from entering the lungs. Meanwhile, the lower esophageal sphincter (LES) relaxes and opens to allow food or liquid to pass through into the stomach.
