Detailed explanation-1: -The hairs present in nasal passage trap the dust particles present in the inhaled air thus allowing only the filtered air to enter into the body. Mucus moistens the air and traps dust particles and kills the bacteria. Q. Mucus lining in the nasal cavity helps in trapping microbes entering our body.
Detailed explanation-2: -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.
