epiglottis closed up to protect food from entering the lungs
The epiglottis.
Epiglottis
It is called the Epiglottis. If you talk while eating, your epiglottis and your esophagus are open, so instead of going down the esophagus, it goes down the epiglottis. Have you ever heard someone say 'It went down the wrong tube' when you choke? This is what they mean.
They both protect food from going into the lungs.
It is the epiglottis.
That's your epiglottis.
Epiglottis
The epiglottis prevents the food you eat from entering the trachea.
When swallowing, the epiglottis closes off the trachea to direct food down the esophagus.
The epiglottis protects the trachea, which handles breathing. When you swallow food, the epiglottis covers the entrance to the trachea so food doesn't get in. Occasionally small bits of food do get in, and that's when you hear people say things like "My food/drink just went down the wrong pipe." Fortunately, for small bits of food like this, coughing it up is usually enough to expel it.
Hakea epiglottis was created in 1805.
