(occurs in oral cavity: stage 2: oral transport: Velum elevates to seal off nasal cavity, food is moved to the back of the oral cavity by the tongue: stage 3: pharyngeal: Epiglottis inverts to protect the airway as bolus is swallowed / moved down the pharyngeal cavity: stage 4: esophageal: Muscle at the top of the esophagus (ues) relaxed to allow the bolus to pass into the stomach. Loss of food/liquid/saliva: oral transport, pharyngeal. Feeling of food getting (cid:862)stu(cid:272)k(cid:863) in the throat.
