Where is the larynx, and what does it do?

The larynx is another name for the voicebox. It forms the top part of the windpipe, to the front of the neck. It is protected by gristly cartilage. The cartilage arches out at the front, and is called the Adam's apple.

When you breathe in through the nose or mouth, air travels through the larynx, down the windpipe, and then into the lungs.

The larynx contains two bands of muscle called vocal cords. When you want to speak, the cords come together, and vibrate as you breathe out. This gives you your voice.
