Which sequence correctly traces the path oxygen takes from the atmosphere to the lungs?

The correct sequence is significant because it accurately represents the anatomical pathway that air, enriched with oxygen, must travel through before reaching the alveoli in the lungs where gas exchange occurs.

Starting with the mouth, air enters the body and then passes through the pharynx, which acts as a conduit for air traveling to the respiratory tract. Following the pharynx, the air proceeds into the trachea, a major airway that directs it down into the lungs. From the trachea, the air divides into the bronchi, which are the larger airways that branch into each lung. Ultimately, the air reaches the bronchioles and then into the alveoli, which are tiny air sacs where oxygen is absorbed into the blood and carbon dioxide is released.

This sequence thoroughly illustrates the necessary structures involved in the respiratory process, highlighting the important role each plays in ensuring oxygen reaches the alveoli for exchange.
