Epiglottis. The epiglottis is a flexible flap at the superior end of the larynx in the throat. It acts as a switch between the larynx and the esophagus to permit air to enter the airway to the lungs and food to pass into the gastrointestinal tract. The epiglottis also protects the body from choking on food that would normally obstruct the airway.

What happens when the epiglottis does not work?
If the epiglottis is absent in the body then the regulation of food material to esophagus and air into the lungs will get disturbed. Sometimes food will enter into the windpipe and then causes choking. Eventually, the lungs cannot not work properly which can lead to death.
Is the epiglottis always open?
It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along the oesophagus toward the stomach instead. It is thus the valve that diverts passage to either the trachea or the oesophagus.
What is the function of the trachea?

What does the larynx do?
The larynx is involved in swallowing, breathing, and voice production. Sound is produced when the air which passes through the vocal cords causes them to vibrate and create sound waves in the pharynx, nose and mouth. The pitch of sound is determined by the amount of tension on the vocal folds.
What is the function of trachea?

Why is the epiglottis important?
Digestion of food - While swallowing food, epiglottis plays an important role. One would want the foods and liquids which we intake to go directly in our stomach rather than going elsewhere to create an unpleasant experience. Here the epiglottis comes into picture as it makes sure that the food enters the esophagus rather than obstructing the windpipe or the airways to the lungs, thereby also preventing choking each time one eats or drinks. Once the person finishes eating, the epiglottis opens up once again and allows for normal breathing.
