Question

Air moves through the respiratory system in a continuous cycle. Which of the following correctly describes the movement of air through the parts of the respiratory system? nose, trachea, bronchioles, alveoli, cells nose, pharynx, alveoli, bronchioles, capillaries trachea, bronchi, pharynx, capillaries, cells trachea, bronchioles, bronchi, alveoli, pharynx

Answer 1

The pharynx would need to come first in order for C to be correct. B is also incorrect. Air flows through the bronchioles, then the alveoli, and finally into or out of the capillaries where gas exchange can occur with cells. A is the only option that correctly describes the path of air through the respiratory system in the correct sequence. The complete flow of air would be: Nose>pharynx>trachea>bronchi>bronchioles>alveoli>gas exchange with cells and then back out.
