Question

State whether True/False.

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 processes that line the upper respiratory tract. Mucous glands and mucosal epithelium in the passage secret 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.
