The answer is the auditory (Eustacean) tube.

It is called the Eustachian tube.
eustation tubes also known as pharyngotympanic or auditory tube
eustachian tube
The EUSTACHIAN tube links the nasopharynx to the middle ear - - it has NOTHING to do with FROGS and TOADS - - - where do you folks come up with these categories?
In humans, the eustachian tube connects the middle ear to a section of the throat known as the pharynx. These tubes are normally closed, but they can open to allow middle ear pressure to reach equilibrium with atmospheric pressure (think of the pops you hear when you drive up a mountain or go up in a plane). They also serve to drain mucus from the middle ear.
The inner delicate part; easily damaged by loud noises and high pressure.

Auditory tube
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
eustachian 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.
