Question

Why do we sneeze ?? Pls tell fast

Answer 1

Answer:

Sneezing is a mechanism your body uses to clear the nose. When foreign matter such as dirt, pollen, smoke, or dust enters the nostrils, the nose may become irritated or tickled. When this happens, your body does what it needs to do to clear the nose — it causes a sneeze.

Answer 2

Answer:

because some dust particles from air go inside of or respiratory tract they are harful for alveoli so the cilia present on treachea take out from respiratory tract so we sneeze
