Epiglottis.
The epiglottis makes sure that food goes down the right tube.When you eat, the epiglottis covers the larynx, so the food or liquid does not enter your lungs. When you breath, the epiglottis stays loose to let the air into the lungs.keep food out of the lungs.
the chicken is bad for you because it blocks your lungs.
Food is kept out of the lungs by a structure in the throat called the epiglottis. It is a flap of skin found just above the vocal chords and larynx (the "windpipe") which leads to the lungs. When a person swallows, the epiglottis folds over top of the vocal cords and blocks off the larynx, preventing food from entering our lungs. Choking, the feeling of having something 'stuck' in your throat, or 'going down the wrong way' can happen because the epiglottis is ONLY a flap of skin that works upon a reflex.

To keep food from going into the lungs.
The epiglottis closes (to stop food going into the lungs) and the muscular walls contract to push the food down the oesophagus.
