Why should you breathe through your nose and not your mouth?
Answer:
When we breathe through the nose, the dust particles, smoke, etc. get stuck in the hair present in the nose, which act as filters. But if we breathe through the mouth, all the dust will enter our body system.
the correct answer is that
We breathe through our nose and not through our mouth because air also contains a lot of dust particles so when we breathe through our nose the dust particles get entangled into the hair present inside our nose but when we breathe through our mouth the dust particles also enter our mouth along with the air.
