Auditory tube
The function of the Eustachian tube is to help equalize pressure on either side of the eardrum. It connects the middle ear to the nasopharynx which is the area of the upper throat behind the nose.
eustachian tube it starts from the middle ear cavity and terminates on nasopharynx.
The Eustachian tube connects the middle ear cavity to the nasopharynx. It aerates the middle ear system into the nasopharynx. Normal opening of the Eustachian tube equalizes atmospheric pressure in the middle ear, closing of the tube protects the middle ear from unwanted pressure fluctuations and loud sounds
