a small airway in the respiratory system that leads from the bronchi to the alveoli in the lungs
What is a "bronchiole"?
A bronchiole refers to a part of the respiratory system in the human body that plays a crucial role in the distribution of air to the alveoli. They are smaller branches of the bronchi, and their walls are composed of smooth muscle, allowing them to regulate airflow and control the amount of oxygen reaching the lungs. The bronchioles serve as a conduit for air, facilitating efficient gas exchange and maintaining proper respiratory function.
Examples
1. These are bronchioles.
2. These bronchioles eventually end in tiny sacs called alveoli.
3. And then you have a bronchiole that's terminating in that air sac.
4. Maybe a bronchiole is terminating in another air sac just like that-- another set of air sacs just like that.
