Question

Sketch larynx and explain its function in your own words.

Answer 1

Larynx is a part of the throat. It is responsible for production of sound. A sketch of a human larynx is shown in the following figure.

Larynx moves when we swallow something. Inside the larynx, there are two vocal cords. There is a small gap between them. This small gap allows air to pass through. When we speak, air is forced into this small gap by the lungs. This prompts vocal cords to vibrate. Since vibrating objects produce sound, sound is produced due to the vibration of vocal cords.
