Question

When a person sees a doctor about a respiratory illness, the doctor will want to determine if the sickness is in the upper respiratory tract or the lower respiratory tract. The starting point for the lower respiratory system is the trachea.

Which structures are part of the upper respiratory system? Select three options.

the larynx
the bronchus
the alveoli
the lungs
the pharynx
the nose

Answer 1

The nose, the pharynx, and the larynx.

(If the lower tract is said to begin at the trachea, then all structures above it — nose, pharynx, and larynx — are part of the upper respiratory tract.)
