Explanation:

The mucous membrane of the paranasal sinuses can respond to environmental stress in multiple ways. It can accelerate mucus production to trap irritants, create swirls and eddies in the sinuses to aid in air - mucus interaction, and break up air flow in the nasal cavity to filter and humidify air better.
