A small muscular flap called the epiglottis closes to prevent food and liquid from going down the “wrong pipe” — your windpipe (trachea). Another small flap called the uvula helps prevent liquid from passing upward into your nasal cavity. Which structure prevents the entry of food in the windpipe?
Full Answer
What prevents food from coming back up?
A ring of muscle fibers in the lower esophagus prevents swallowed food from moving back up. These muscle fibers are called the lower esophageal sphincter (LES). When this ring of muscle does not close all the way, stomach contents can leak back into the esophagus.

What organ prevents food and water from going into your lungs?
the epiglottisA small flap of tissue called the epiglottis (eh-pih-GLAH-tus) protects the larynx. When we swallow, the epiglottis covers the larynx to prevent food and liquid from going into the lungs.
What is the role of larynx?
Your larynx has three main functions in your body: Breathing. Creating vocal sounds. Preventing food and other particles from getting into your trachea, lungs and the rest of your respiratory system.
What is a role of epiglottis?
The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs.
What is glottis and epiglottis?
The glottis is the narrowest part of the larynx and opens into the airway. Vocal cords make lateral borders of it. Epiglottis, a leaf-shaped cartilaginous flap, prevents the food to enter the airway passage of the respiratory system while swallowing.
Is trachea and larynx the same?
The larynx is the upper opening into the windpipe (trachea), the passageway to the lungs.
Who prevents the entry of food into larynx?
EpiglottisEpiglottis is a tiny flap of cartilaginous tissue attached to the entrance of the larynx, and covers it during swallowing, to prevent the entry of food into the air tract.
Who prevents the entry of food into the glottis?
epiglottisA cartilaginous flap called epiglottis specifically prevents the entry of food into the glottis (opening of the windpipe) during swallowing.
What do you call an organ that prevents food from entering the larynx?
epiglottis - large , leaf-shaped piece of cartilage lying on top of larynx; during swallowing the larynx elevates, causing the epiglottis to fall on the glottis (opening into larynx) like a lid, closing it off - this prevents food from entering the windpipe (trachea).
