 Why do people burp?

Whats the Epiglottis and what does it do?
It slipped my mind....what does it do and what is it?

It keeps food from coming up your throat.

Glotis is above the stomach and then the Epiglottis is the closing of your throat. Keeps food from going into your lungs when you are eating.

Part of your digestive system throat down to stomach..

The thin elastic cartilaginous structure located at the root of the tongue that folds over the glottis to prevent food and liquid from entering the trachea (wind pipe) during the act of swallowing.

The epiglottis is a lid-like flap of elastic cartilage tissue covered with a mucous membrane, attached to the root of the tongue.It guards the entrance of the glottis, the opening between the vocal folds.

It prevents food from going into the trachea and instead directs it to the esophagus.
The epiglottis is one of nine cartilaginous structures that make up the larynx (voice box).

The epiglottis is a small flap of muscle, attached to the back of the tongue. Its role is to fold over the trachea (wind pipe) when we swallow to prevent food from entering the lungs.

This is an answer I gave to someone that asked a question about how food stays out of your throat when You swallow, but I think it answers your question as well.

The epiglottis guards the entrance of the glottis, the opening between the vocal cords, during swallowing.

It is normally pointed upward, but during swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is more posterior.

This mechanism can be flawed in people with swallowing problems. They have trouble with their epiglottis closing properly which causes them to aspirate food into their trachea. These people are usually put on special diets where their food is chopped up or pureed for them.

Have a good day!!
