What is bronchi and bronchioles?
Bronchi are the main passageway into the lungs. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
Considering this, what is the function of bronchi and bronchioles?
The task of the bronchi is to ensure the passage of air from the trachea to the bronchioles.
