Question

Short answer question.

Why is it advantageous to breathe through the nose than through the mouth?

Answer 1

i. Nose filters and warms the inhaled air. Hair in the nose prevents the entry of microbes, dust, and other impurities which may harm the lungs.

ii. Mouth lacks any such structures for filtering and warming the air that is inhaled during inspiration. Hence, it is advantageous to breathe through the nose than through the mouth.
