Question

Quizplus · Accepted Answer

Bronchioles are small, narrow tubes in the respiratory system that play a significant role in regulating airflow through the air passageways. They are responsible for regulating the amount of air that enters and exits the lungs and are a key component of the respiratory system. The diameter of bronchioles can change in response to various stimuli, which allows for fine-tuning of airflow to meet the body's oxygen demands. Alveolar ducts, trachea, and lobar bronchi are also important parts of the respiratory system, but they do not play as direct a role in regulating airflow as bronchioles do.
