प्रश्न
Why is it better to breathe through your nose than your mouth?
उत्तर
It is better to breathe through our nose than our mouth because our nasal cavity is lined by hair. The air we breathe in contains fine dust particles. These particles get trapped in the hair in the nasal cavity and are thereby prevented from reaching the lungs. The inside of the nose is also covered by a sticky fluid called mucus. Dust and germs stick to the muscles and thus, the air taken in is cleaned. The air is also warmed up by blood vessels present in the nasal cavity
