Question

Examlex · Accepted Answer

The Answer is Presence of food in the oropharynx stimulates the deglutition center in the medulla and pons to move the soft palate and uvula upward to close off the nasopharynx,thus keeping food out of the nasal cavity.At the same time,the larynx rises and the epiglottis moves down and back to seal off the larynx,which is further closed by the vocal cords,thus keeping food from entering the lower respiratory tract.
