Answer:

sorry I know that cilia Are the locomotory structure of paramecium I don't know according to the respiratory system but for paramecium, it creates a current in gullet and helps the microbes to engulf the food

Cilia protects the nasal passageways and other parts of the respiratory tract. It filters out dust and other particles that enter the nose through the breathed air. Cilia propels a liquid layer of mucus that covers the airways. The mucus layer traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.
