Bronchioles are the gateways into the lungs and these gateways modifies into tiny air sacs called alveoli in the lungs. The Brionchioles is the site for the exchange of oxygen and carbon dioxide in the lungs. They play a cognizant role in ensuring that air coming into the alveolus reach each one of them.
