Food trying to escape down your trachea instead of your esophagus? That's when your epiglottis says "not on my watch" and triggers the cough reflex. Meanwhile, your larynx is just standing there like "I told you this would happen." The epiglottis is basically the bouncer of your throat, making sure food goes to the stomach club, not the lung lounge. Evolution really nailed that design... except when it didn't and you're choking on water somehow.
