As air is inhaled, the sequence in which it passes through the respiratory tract is best described by which of the following choices?

A Nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles.

When inhaling, air is taken in through the mouth and nose, and then through the larynx and pharynx. These passageways warm the air and prepare it for gas exchange. The air continues on through the trachea, commonly referred to as the “windpipe”. The trachea then splits into a right and left bronchi, with each side dividing further into smaller bronchioles. While some bronchioles may directly be involved in gas exchange, the majority of them are part of the conducting airway, which simply moves air through the respiratory system to get them to the alveoli where most of the gas exchange occurs.
