Final answer:
The correct order in which inhaled air travels through the respiratory system is nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli. The pharynx serves both respiratory and digestive functions, while the larynx houses the vocal cords and is also called the voice box.
Step-by-step explanation:
Order of Airflow During Inhalation
The correct sequence through which air passes during inhalation is as follows: nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and finally the alveoli. To clarify, the pharynx is a tube-like structure that connects the nasal cavity with the larynx and is part of both the respiratory and digestive systems. Following the pharynx, air passes through the larynx, also known as the voice box, which houses the vocal cords. After the larynx, air moves through the trachea, then into the bronchi, which are the main passages into the lungs, and finally through the smaller bronchioles until reaching the alveoli where gas exchange occurs.
