Question

Q3. Our nostrils have hair and mucous. What is the need to have them in our nasal cavity?​

Answer 1

Answer:

Explanation: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.
