The glottis and the epiglottis are two components of the pharynx which play a crucial role in ensuring the safety of our airways during the process of swallowing food. The glottis, being the narrowest part of the larynx, provides an opening to the airway and is bordered by the vocal cords. On the other hand, the epiglottis, a leaf-like cartilaginous flap, safeguards the airway passage of the respiratory system by preventing food from entering it while swallowing. The larynx muscles contract during swallowing, which results in the upward movement of the glottis and the downward movement of the epiglottis. This article will delve into the differences between the glottis and the epiglottis.

Comparing the Glottis and the Epiglottis
| Glottis | Epiglottis |
| The glottis provides an opening to the airway | The epiglottis is the superior border of the glottis |
| The voice type is determined by the size of the glottis | The size of the epiglottis doesn't affect the voice type |
| During swallowing, the glottis moves upward | The epiglottis moves downward when swallowing |
The glottis, which opens into the windpipe, is instrumental in the production of sound. The epiglottis, a cartilaginous flap that sits atop the glottis, functions to prevent food from entering the larynx. The primary distinction between the glottis and the epiglottis lies in their respective functions and structures.

Frequently Asked Questions
What is the difference between glottis and epiglottis?
Glottis is the narrowest part of the larynx and opens into the airway, while the epiglottis is a leaf-shaped cartilaginous flap that prevents food from entering the airway passage while swallowing.
What is the function of the glottis and epiglottis?
The glottis opens into the windpipe and is responsible for the production of sound. The epiglottis prevents the food from entering the larynx while swallowing.
Do the glottis and epiglottis affect voice type?
Yes, the size of the glottis is responsible for the voice type, whereas the size of the epiglottis is not.
