Question

The reason for breathing in through your nose and out through your mouth

In: Biology

Answer 1

The nose has mucus and air to filter out dust and bacteria. Also the nose’s insides are a bit warmer and damper than the mouth so that the air is a bit easier to breathe in and to prevent pneumonia.

Basically, nose boogers are just a ball of nasty stuff that would’ve gone through of you’d have breathed through your mouth.
