Epiglottis
The flap-like structure that prevents food from going the wrong way during swallowing is called the epiglottis. It is a thin, leaf-shaped piece of cartilage located at the base of the tongue. During swallowing, the epiglottis folds down over the trachea (windpipe) to ensure that food and liquids are directed into the esophagus and not into the airway. This action helps prevent choking and aspiration.
to do a flip flap you press up and then down down then up for a flap flop
There is a flap that connects the esophogus with the trachea. The flap opens when you breathe or talk. The flap closes when you swallow food. If you talk or breathe while you eat food. the flap opens and food goes down to your lungs. Then, you choke.

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.
The flap of tissue that closes when you swallow is called the epiglottis. It is located at the base of the tongue and helps to prevent food and liquids from entering the trachea (windpipe) during swallowing, directing them instead to the esophagus.
The epiglottis is a flap of tissue at the back of the throat that prevents food from going into trachea when being swallowed .
The flap that covers the trachea is called the epiglottis. Its main function is to prevent food and liquid from entering the trachea when swallowing, ensuring these substances go down the esophagus instead.
The epiglottis is a flap that acts like a "door" and seals off your airway while you are swallowing food, and then opens to allow you to breathe when you are not swallowing food. When you are eating, make sure that you do not talk, as this interferes with the function of the epiglottis and can cause food to enter your airway.
