Okay if I get what you are saying, there is a little flap called the epiglottis that switches between covering the esophagus and trachia. When you are eating food this flap covers the trachia so you don't get food in your lungs (that would be very bad) and when you're just breathing normally the epiglottis covers your esophagus so you can actually breath. I you think you have a problem with your epiglottis then go to the doctor immediately. Hoped this answered your question. If not well you just learned something new today! ^_^
