epiglottis
covers the trachea to prevent food going down
The epiglottis is a small, leaf-shaped flap of tissue located at the base of the tongue and above the larynx (voice box). Its primary function is to prevent food or liquids from entering the trachea (windpipe) and lungs during swallowing.
When food or liquid is swallowed, the epiglottis moves downward and covers the opening of the larynx, directing them into the esophagus (food pipe) and stomach. This mechanism prevents choking and aspiration pneumonia.
It is important to note that some medical conditions such as cancer, infections, and injuries can affect the functioning of the epiglottis, leading to difficulty in swallowing and breathing. Therefore, if someone experiences any symptoms related to the epiglottis, they should seek medical assistance immediately.
