The epiglottis blocks the entrance to your windpipe when you swallow. This action prevents food from entering your trachea instead of your esophagus.

Why does the Epiglottis move and what are its functions?
It is normally pointed upward during breathing with its underside functioning as part of the pharynx, but during swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position, with its superior side functioning as part of the pharynx. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is at the back. The glossopharyngeal nerve (CN IX) sends fibers to the upper epiglottis that contribute to the afferent limb of the gag reflex. The superior laryngeal branch of the vagus nerve (CN X) sends fibers to the lower epiglottis that contribute to the efferent limb of the cough reflex.
Swallowing?
The structures involved with the process of swallowing include the tongue, teeth, epiglottis, and esophagus.The teeth are used to grind and chop up food into tiny pieces, while the glands in the mouth moisten the food with saliva. In the first stage of swallowing, the tongue pushes the food into the throat. In the second stage of swallowing, an important small flap of tissue called the epiglottis, folds over the voice box (larynx) at the entrance to the windpipe (trachea), preventing food from going down the wrong way. In the final stage, the esophagus contracts and moves food toward the stomach.Reviewed ByReview Date: 10/20/2009David C.

Why is the inside of the mitochondria have folds?
Folds increase surface area.So it increase the rate of respiration.
Most of our bodies enzymes are produced where?
The enzyme's surface folds are complementary to the substrate's surface folds.
What are gastric folds?
Gastric folds are found in the interior of the stomach. They are also know as gastric rugae.The main importance of gastric folds is to increase the stomach's surface area and allow it to expand.
How does the epiglottis behave?
It folds over the trachea during swallowing to prevent food from entering the windpipe.
How does epiglottis behave?
It folds over the trachea during swallowing to prevent food from entering the windpipe.
The function of the epiglottis is to?
The epiglottis is what guards the entrance of the opening in the vocal folds. During the action of swallowing, it allows food to pass and go down the esophagus.
Why is the epiglottis imporent?
The epiglottis guards the entrance of the glottis, the opening between the vocal folds and the entrance to the lungs.=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 position it prevents food from going into the trachea and instead directs it to the esophagus, which is more posterior, into the stomach.=
What happens to the larynx as you swallow the food you eat?
There is a piece of cartilage called the epiglottis which folds over the opening of the larynx as the person is swallowing. This prevents food from going into the windpipe.
What is the epigollatus?
If you meant epiglottis, then it is a flap a cartilage located behind your tongue and in front of the larynx. The epiglottis is fairly important for the respiratory and digestive system, because it serves as a gate for the trachea and the esophagus. When the epiglottis is in a resting position is allows air to pass into the larynx and the lungs, but when a person swallows the epiglottis folds up and allows for food and liquids to enter the esophagus, and not the windpipe.
What is the structure and function of the epiglottis?
The epiglottis guards the entrance of the glottis, the opening between the vocal folds. It is normally pointed upward while one is breathing with its underside functioning as part of the pharynx, but while one is swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position, with its superior side functioning as part of the pharynx. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is posterior.
What keeps food from going down our windpipe?
Food is kept out of the lungs by a structure in the throat called the epiglottis. It is a flap of skin found just above the vocal chords and larynx (the "windpipe") which leads to the lungs. When a person swallows, the epiglottis folds over top of the vocal cords and blocks off the larynx, preventing food from entering our lungs. Choking, the feeling of having something 'stuck' in your throat, or 'going down the wrong way' can happen because the epiglottis is ONLY a flap of skin that works upon a reflex.

What is the difference between the epiglottis and the glottis?
The epiglottis "directs traffic". It is the flap that covers the larynx to prevent the passage of food and liquids. The glottis Also called the glottic cleft, is the space between the vocal folds & arytenoid cartilages of the larynx where speech takes place. The epiglottis is the flap of cartilage covered by a membrane that is attached to the entrance of the larynx. The glottis is part of the larynx that is made up of the vocal cords. glottis is the hole, epiglottis is the flap. epiglottis flap open = air " " closed = food
What stops food entering the lungs?
The epiglottis normally keeps this from happening.* How The Epiglottis Works:When you swallow, a small flap - called the epiglottis - briefly covers the top of the windpipe (or trachea) so that food goes the right way, into the digestive system, and not the wrong way, into the respiratory tract.The flap can't stay down all the time, or you would not be able to breathe! Sometimes a little food or liquid does get into the windpipe - perhaps if you ingest it very quickly - and that's when you cough to get it out again.When you swallow, the epiglottis should automatically cover the windpipe, so swallowing is a good way to suppress a cough if you are somewhere where you don't want to make a noise...
What is epigottis?
The epiglottis is a flap of cartilage at the base of the tongue. It points upward except when solids and liquids pass from the mouth into the esophagus. The epiglottis folds down over the glottis to prevent food from passing into the lungs through the trachea.
Is the epiglottis is one of the muscles of the face?
No, it is"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 during the act of swallowing."Read more: epiglottis
