Based on my analysis, I began moving down the respiratory tract. The inhalation of air from the patient started me off as I soon proceeded past the pharynx and the epiglottis, entering the larynx down to the trachea and swerved into the left bronchi. Everything started to get closer and compacted as the path decreased in size along the progression towards the bronchiole and the alveoli. Closing towards the thin membranous wall of the alveolus, particles and other substances began to disappear amidst my awareness, diffusing to the other side.

Like public transportation, A red blood cell came by and carried the vesicle towards what could possibly be the right pulmonary vein.
