  16. 16. • Primary bronchial are linked with cilia or very small hair. It has wave like motion. It carries liquid upward and out into throat Where it either coughed or swallowed
  17. 17. • The diaphragm is wall of muscle that separate the chest cavity From abdominal cavity.• Diaphragm creates suction to drew in air and expand the lung.
  18. 18. • Bronchioles is smallest subdivision of the bronchi. at the end of which are alveolus.
  19. 19. • Alveoli are small sacs that are the distention of breathing in
