Question

air is carried between the pharynx and bronchial tubes in the:
a epiglottis.
b trachea.
c nasal cavity.
d esophagus.

Explanation:

The trachea, also known as the wind - pipe, is the airway that connects the pharynx and larynx to the bronchial tubes, allowing air to pass. The epiglottis is a flap that prevents food from entering the trachea during swallowing. The nasal cavity is part of the upper respiratory tract for air intake and filtering. The esophagus is for food passage, not air.

B. trachea
