During deglutition (swallowing), all of these processes occur: the soft palate elevates to prevent food from entering the nasal cavity, the larynx elevates and the epiglottis closes to prevent food from entering the trachea, the lower esophageal sphincter opens to allow food into the esophagus, and smooth muscle contracts to move the bolus of food down the esophagus.
