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.

Food is prevented from going down the winpipe because the epiclottis.
A small muscle in the back of your throat called the epiglotis.
The food and beverages that go down the food pipe are prevented from entering the wind pipe with the help of epiglottis. When we swallow, the flap of cartilage shuts down automatically, causing it to reach the digestive system.
There are two reasons this doesn't happen. One is that you cannot breate while swallowing, and the other is that the body has an involuntary reflex that prevents it from inhaling food.

Epiglottis
epiglottis
The epiglottis is a flap of tissue that prevents food from entering the windpipe (trachea) when swallowing. It acts as a cover for the trachea, ensuring that food only goes down the esophagus to the stomach.
an esophagus keeps food from going down your airway.
Epiglottis...
The flap that prevents food from entering your windpipe is called the epiglottis. It is a leaf-shaped structure located at the base of the tongue that closes off the trachea during swallowing to ensure that food goes down the esophagus instead.
It's the part of your body that flops down over the windpipe when you swallow to keep food from going into your lungs.
