Solution (3)The smallest respiratory bronchioles subdivide into t.pdf

Solution
:
(3)The smallest respiratory bronchioles subdivide into thin airways called alveolar
ducts.Alveolar sacs are connected to respiratory bronchioles by alveolar ducts.It helps alveoli in
process of gas exchange.Alveolar duct transport inhaled air filled in it to the alveoli and after the
process of gas exchange completed alveolar duct exhibit carbon dioxide gas..
