Verified step by step guidance

Begin by understanding the anatomy of the respiratory system, which is responsible for the process of inhalation.

Identify the structures involved in the pathway of airflow during inhalation: nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.

Recognize that inhalation starts at the nasal cavity, where air is filtered, warmed, and humidified.

Follow the airflow as it moves from the nasal cavity to the pharynx, which serves as a passageway for air to reach the larynx.

Continue tracing the airflow from the larynx to the trachea, then into the bronchi, bronchioles, and finally reaching the alveoli where gas exchange occurs.
