Question

Quizplus · Accepted Answer

The bronchioles are the final branches of the respiratory system before reaching the alveoli where gas exchange occurs. The larynx, trachea, and bronchi are all earlier structures in the respiratory system. The pharynx is not directly involved in the movement of air into the lungs, as it is part of the digestive system.
