MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles.

Detailed explanation-3: -Mucus captures dust, germs, and other small particles that could irritate your lungs. If you look inside your nose, you will also see hairs that can trap large particles, like dirt or pollen.

Detailed explanation-4: -The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
