Yes it does.
Yes :)
The answer is the auditory (Eustacean) tube.
eustation tubes also known as pharyngotympanic or auditory tube
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.
eustachian tube
Dorsally, the neck contains the esophagus and the ventral to the esophagus is the larynx, which leads to the trachea. The esophagus is a flexible muscular tube connecting the pharynx to the stomach. Meanwhile, air moves from the larynx to the trachea to the lungs when you inhale, and the from the lungs to the trachea to the larynx when you exhale.

The middle ear & the nasopharynx
It is important that the auditory tubes and the sinuses drain into the nasal cavities and nasopharynx because otherwise they would become blocked with mucus and prevent respiration.
To permit drainage away from the ear drum membrane.
The ear -- specifically, the back of the eardrum or tympanic membrane
Auditory tube
Auditory information is processed through the ears and transmitted to the brain for interpretation.
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.
The auditory tubes mark the opening of the nasopharynx in the fetal pig. The purpose of these tubes is the beginning of development for the ears.
