Question

'Nose is better in breathing than mouth.' Comment.

Answer 1

Here is your answer....

Yes, Exhaling through the nose, which is smaller than the mouth, creates greater air pressure and therefore a slower exhalation. This gives the lungs extra time to extract a greater amount of oxygen.

Hope it helps you.

Answer 2

Hy  Because the nostrils are smaller than the mouth, air exhaled through the nose creates a back flow of air (and oxygen) into the lungs. And because we exhale more slowly through the nose than we do though the mouth, the lungs have more time to extract oxygen from the air we've already taken in.
