Question

what is the role of hair and mucus inside the nose​

Answer 1

Answer:

The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.

Answer 2

Answer:

The hair present in our nose prevents dust particles from reaching our lungs through trachea and mucous present in it warms the air. Hope this helps you ☺.
