Question

the portion of the respiratory system that connects the nasal and oral cavities to the larynx is the

Explanation:

The pharynx is a part of the respiratory system. It is a muscular tube that serves as a common passageway for air and food. It connects the nasal cavity (nasopharynx part) and oral cavity (oropharynx part) to the larynx (laryngopharynx part). The bronchus is part of the lower respiratory tract branching from the trachea. The trachea is the windpipe that leads to the bronchi. The auditory tube connects the middle ear to the nasopharynx and is not mainly a respiratory - system connection between nasal/oral cavities and larynx.

Answer:

pharynx
