During expiration, air is expelled from the lungs in a specific order as it travels through the respiratory structures. The correct sequence starts from the bronchi, where the air is located after gas exchange has occurred in the alveoli. From the bronchi, the air moves into the trachea, which is the central airway leading to the outside environment. Next, the air passes through the larynx, commonly known as the voice box, where it may be manipulated for sound production and, occasionally, some filtering. Finally, the air exits through the pharynx, which serves as a passageway to the outside. This order highlights the pathway through which air travels as it leaves the lungs. Understanding this route is crucial for grasping the mechanics of breathing and how the various components of the respiratory system function together during expiration.
