What is the main function of the larynx?

The main function of the larynx is to produce sound and protect the trachea. The larynx, often called the voice box, is situated in the neck and plays a crucial role in phonation. It houses the vocal cords, which vibrate to create sound when air passes through them. This ability to produce sound is essential for communication.

In addition to its role in sound production, the larynx serves as a protective mechanism for the trachea. It acts as a barrier, preventing foreign objects and substances from entering the airway during swallowing, thus safeguarding the vital respiratory structures. This dual function of voice production and airway protection highlights the significance of the larynx within the respiratory and vocal systems.
