Voice prosthesis valve - image description

The illustration shows a cross section of a person’s head and neck area. The person is facing to the left. There is no larynx and the windpipe curves slightly to the front where it ends as an opening in the neck, called the laryngectomy stoma. The person has their finger over the laryngectomy stoma. The diagram shows the oesophagus, also called the gullet,  going from the back of the mouth area and going down behind the windpipe. There is a valve linking the windpipe to the gullet. This is called the voice prosthesis vale. There are arrows going up the windpipe, through the valve and up the top part of the gullet and out through the mouth. This indicates where air goes as it is breathed out so the person can speak through their mouth.
