Question

Give reason
1)Bronchioles terminate into alveoil

Answer 1

Each terminal bronchiole separates to create respiratory bronchioles that have alveoli, which are small, balloon-like sacs at the end of the small air passages in the lungs (the bronchiole). Oxygen is inhaled and absorbed into the bloodstream through the thin walls of each alveolus, by way of the pulmonary veins. Carbon dioxide from the pulmonary artery is exhaled as a waste product of the lungs.

Answer 2

Answer:

The segmental bronchi divide into many primary bronchioles that divide into terminal bronchioles, each of which then gives rise to several respiratory bronchioles, which go on to divide into and terminate in tiny air sacs called alveoli.
