ANATOMY

Detailed explanation-1: -Nasal hair or nose hair, is the hair in the human nose. Adult humans have hair in the nostrils. Nasal hair functions include filtering foreign particles from entering the nasal cavity, and collecting moisture.

Detailed explanation-2: -Nose hairs act as a filter that prevents dust, pollen, and allergens from entering your lungs. When particles enter your nose, they get stuck on a thin layer of mucus that coats your hairs. Eventually, the particles either get sneezed out or swallowed. Your nose is also filled with microscopic hairs called cilia.

Detailed explanation-3: -Nasal hair is the hair inside the nose. It is one of the body’s first line of defence against harmful environmental pathogens such as germs, fungus, and spores that are inhaled. Another purpose of nasal hair is to provide additional humidity to the inhaled air.

Detailed explanation-4: -Air enters the respiratory system through the nose or the mouth, then travels down a pathway to the lungs. In the nostrils, air gets warmed and moistened. Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles.

Detailed explanation-5: -The hair and mucus that are present inside the nose filter the air that goes into the lungs. That is, these stop the germs and dust from entering into our body.
