Answer 2

Answer:

we should breathe through our nose not from the mouth because our nose has small hairs inside our nose which don't allow the dust particles to enter in our body. whereas in mouth their is no such protection and we can inhale many dust particles while breathing from our mouth and can cause many health diseases.
