What is the Epiglottis? Epiglottis Structure and Function
Learn More About Simplified Science PublishingThe epiglottis is a piece of cartilage that covers the entryway to your trachea and lungs. The purpose of the epiglottis is to stay closed when saliva and food are moving to your stomach.
What is the epiglottis?
If you’ve ever taken a sip from a drink and accidentally laughed at the same time, you probably experienced an uncontrollable coughing fit that caused tears to stream down your cheeks. This unpleasant event is due to the poorly timed opening of your epiglottis (eh-pih-glah-tis). The epiglottis is the primary protector of the airways, your lung guardian and breathing gate. Essentially, your epiglottis is your breathing bouncer.
The epiglottis is a leaf-shaped piece of cartilage that covers the entryway to your larynx and trachea. If your breathing bouncer opens at the same time that saliva and food particles are sliding past, some of the stuff can slip into your airway, which causes coughing and irritation. In a worse-case scenario, an inappropriate opening of your epiglottis can also allow a large piece of food to become lodged in your windpipe, which causes you to choke. Thankfully, the epiglottis is remarkably good at its job and rarely allows intruders into your air tubes.
