The Eustachian tube is a tube which is connected from the middle ear to the throat. In a average adult the Eustachian tube is approximately 35 mm long. Usualy the opening of the Eustachian tube is kept closed but only opens when the human either swallows or yawns. It allows air from the ear to escape so the ear does not get damaged by the amount of pressure applied to it.
