Question

terminal bronchioles divide into (in the correct order)...
multiple choice
alveolar sac, alveolar duct, respiratory bronchiole
alveolar duct, respiratory bronchiole, alveolar sac
alveolar duct, alveolar sac, respiratory bronchiole
respiratory bronchiole, alveolar duct, alveolar sac

Explanation:

In the respiratory system, the terminal bronchioles first divide into respiratory bronchioles. These respiratory bronchioles then further divide into alveolar ducts. Finally, the alveolar ducts lead to the alveolar sacs. This sequence is based on the anatomical structure and the pathway of the respiratory tree.

Answer:

Respiratory bronchiole, alveolar duct, alveolar sac
