Question

Trace the airflow of respiratory system starting with the external nares?

Answer 1

I will be happy to read and correct through your approach :-)

Answer 2

This is what I thought:

1. external nares
2. nasal cavity
3. internal nares
4. nasopharynx
5. oropharynx
6. laryngopharynx
7. larynx
8. trachea
9. primary bronchus
10. secondary bronchus
11. tertiary bronchus
12. bronchiole
13. terminal bronchiole
14. respiratory bronchiole
15. alveolar duct
16. alveolar sac
17. alveolus

But I'm not sure if there may be some errors in there.

Answer 3

it looks correct from my non-expert point of view, I didn't miss anything I would've expected. you even specified the pharynx into sub-groups...I didn't know you needed to do that :D

the order of terms is right. if you have a very accurate teacher he might expect words I've never heard before ^^ but your answer seems fine.

Answer 4

Ok. Thanks!
