Question

Hey guys ......Good evening. ..... Why is it advisable to breathe from our nose and not from mouth ??​

Answer 1

Because the nostrils are smaller thanthe 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.

please mark this as brainliest answer and thank me and follow me

Answer 2

Because In Nose There is a Dirt Particle Which traps The Dirty Things Present in Air and Let to go to the lungs So Doctor advice is to breathe With Nose.
