Final answer:

Air during inhalation follows the path: mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli. The bronchioles lead to alveoli, where gas exchange occurs, not to bronchi.

Step-by-step explanation:

The correct path through which air moves during inhalation is: mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli. Air enters the body through the mouth or nose and then moves to the pharynx. From the pharynx, it travels to the larynx and down the trachea, also known as the windpipe.

The trachea splits into the right and left bronchi as it enters the lungs. Each bronchus then divides into smaller tubes called bronchioles, which lead to tiny air sacs known as alveoli where gas exchange occurs. It is important to note that bronchioles are branching structures that lead from the bronchi to the alveoli, not the other way around. Therefore, option A) mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli is the correct sequence describing the path of inhaled air.

The correct order of the structures through which air moves during inhalation is:

mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli.
