During deglutition, or swallowing, the soft palate elevates to close off the nasal passage and prevent food from entering the nasal cavity. The larynx also elevates to accommodate the passage of food and the epiglottis closes to prevent food from entering the trachea. Finally, the lower esophageal sphincter relaxes to allow food to enter the esophagus. Therefore, all of the above statements are true.
