This tube is larger than your thumb and is named the larynx, or voice box.
While the sound is being made, there will be a slight upward pulling of the voice box, a slight tugging at the voice box.
Always think twice before you let anything unpleasant or unkind come out of your voice box.
Whenever you like, you can blow out your breath between these folds of skin in your voice box.
Of course the muscles of the mouth and throat, and the teeth and the tongue all help the voice box as much as they can.
From the voice box extends the windpipe called trachea, down to the lungs.
