Question

The following defines the upper respiratory system in appropriate order:

A)
Nose, epiglottis, trachea, lobes of lungs, pleura and bronchi

B)
Nose, pharynx, larynx and trachea

C)
Nose, pharynx, epiglottis, larynx, trachea, lobes of lungs, primary bronchi, secondary bronchi and alveoli

D)
Nose, pleura, pharynx, larynx, epiglottis, trachea, lobes of lungs, primary bronchi and secondary bronchi

Answer 1

The correct order of structures in the upper respiratory system through which air passes during inhalation is B) Nose, pharynx, larynx, and trachea.

Step-by-step explanation:

Among the options provided for the order of the upper respiratory system, the correct choice is B) Nose, pharynx, larynx, and trachea.

This option accurately delineates the correct path that air takes during inhalation before reaching the lower respiratory system.

For further clarity, here is a step-by-step path that air follows upon entering the body: Air enters through the nasal cavity (or mouth), moves into the pharynx (throat), passes through the larynx (voice box), and finally travels down the trachea (windpipe), before heading into the lower parts of the respiratory system.
