What is considered the main trunk of the respiratory system?
Since this is not my area of expertise, I searched Google under the key words "<I>'respiratory system' main trunk</I>" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
