The eustachian tube connects the nasal cavities with the?

• A. Pharynx.
• B. Ear.
• C. Esophagus.
• D. Larynx.

Answer: (B)

The eustachian tube teaches you how the middle ear stays ventilated and pressure-balanced with the outside world. It runs from the middle ear cavity to the nasopharynx, the upper part of the throat just behind the nasal cavities. Because its direct connection is between the middle ear and the nasal region, the ear is the correct endpoint described. It’s not a direct connection to the esophagus or larynx.
