Explain why food does not normally go up into your nasal cavity or down into your lungs when you swallow-even if you are standing on your head when you swallow.

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.
