Bronchioles: The essential airway passages in the respiratory system

Marshal Mack

Bronchioles are small airways in the lungs that help to facilitate the movement of air in and out of the respiratory system. These small tubes branch off from the larger bronchi and divide into smaller passages called alveolar ducts that eventually lead to tiny air sacs called alveoli. Bronchioles play a crucial role in breathing by regulating the flow of air in and out of the lungs. They are responsible for carrying air to the alveoli, where oxygen and carbon dioxide are exchanged with the blood. The bronchioles also play an important role in protecting the lungs from harmful particles, such as dust and bacteria, by producing mucus and cilia
