Question

Beating movement of cilia is necessary for clearing pathogens from the nasal passage.

• A. True
• B. False

Answer 1

The correct option is A True

Cilia are minute hair-like structures that line the upper respiratory tract. Mucus glands and mucosal epithelium in the passage secrete mucus which is sticky and traps pathogens entering the nasal passage when we breathe in. This mucus is then thrown out of the nasal passage as the cilia beat back and forth clearing the pathogens from the body.
