Final answer:
The air enters the respiratory tract through the nose, subsequent to which it travels through the pharynx, larynx, trachea, bronchi, and finally bronchioles before reaching the alveoli for gas exchange.
Step-by-step explanation:
The point at which air enters the respiratory tract is referred to as the nose or nasal cavity, which is not one of the options provided in the original question. However, the pharynx is the subsequent passageway that air travels through after the nose. The correct order in which inhaled air travels from the pharynx is as follows: the air passes through the pharynx, then through the larynx (also known as the voice box because of the vocal cords present), followed by the trachea, which then divides into two main bronchi leading to each lung, and finally air continues down the smaller bronchioles before reaching the alveoli for gas exchange.
When considering the options provided in the question, the correct sequence would be pharynx → larynx → trachea → bronchi → bronchioles.
