What function does the larynx serve in the human body?

The function of the larynx, often referred to as the voice box, is primarily associated with the production of sound. It contains the vocal cords, which are essential for phonation. When air is expelled from the lungs and passes through the closed vocal cords, it causes them to vibrate, producing sound. This mechanism is fundamental for speech and vocalization, making the larynx crucial in communication.

While the larynx also plays additional roles, such as assisting with breathing and providing a protective function for the airway during swallowing, its main anatomical significance is centered around voice production due to the presence of the vocal cords.
