___________ Play an Important Role in Regulating the Airflow Through

Question

___________ play an important role in regulating the airflow through the air passageways.
A)Alveolar ducts
B)Trachea
C)Bronchioles
D)Lobar bronchi

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.
