The anatomical region that begins roughly at the base (back) of the tongue and goes down to the level of the upper part of the trachea/esophagus low in the neck. The laryngopharynx comprises an area in which both breathing and swallowing functions are shared. When one reaches the larynx/esophagus, at that point begin separate and dedicated passages for air and food.
