Question

In addition to mucus, what helps your nose to filter out germs and dirt?

• A. Tiny Hairs
• B. Blood
• C. Skin Cells
• D. Melanin

Answer 1

The correct option is A

Tiny Hairs

We inhale the air through our nose. Inhaled air may contain dust, dirt, germs or pollen. The lining of the nasal cavity contains cilia and mucus. The mucus traps incoming unwanted particles, which are then moved by the cilia toward the front of the nose or down the throat to be removed from the airway.
