a:  nasal cavity ~
b:  air filter
What:  
"Sinuses and Nasal Cavity, is like changing the car cabin air filter which is done once in a while. Get a kit at the drug-store which has a bottle with a head that you can shoot water with saline up there. The fleshy part just inside the corner of your eyes is part of the sinus and a booger will be stuck up at the top of that nasal cavity."
