The Eustachian tube connects the middle ear space to the upper part of the throat. III
The upper part of the throat is called the nasopharynx. It is located behind the nose and above the soft palate. The nasopharynx serves as a passage for air from the nasal cavity to the throat and plays a role in the respiratory system. It also connects to the middle ear via the Eustachian tubes, helping to equalize pressure.
