   Bronchiole

   • The bronchioles are responsible for carrying air to the alveoli.
   • In asthma, the bronchioles can constrict, making breathing difficult.
   • The infection spread to the bronchioles, causing bronchiolitis.
   • Each bronchiole ends in a cluster of tiny air sacs called alveoli.
