Question

4. The mucous in the nasal cavity helps in removing germs from the inhaled air​

Answer 1

Answer:

The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Answer 2

Answer:

A mucous membrane lines your nasal cavity and it helps keep your nose moist. Little hairs inside your nasal cavity help filter the air you breathe in, and block dirt and dust from getting into your lungs. When you breathe in through your mouth, or oral cavity, the air is moistened, but not filtered.
