They are arranged so that the breathing air is pulled through them. But if you deliberately want to smell something, for example a flower, we usually breathe in strongly through the nose and thereby direct flow of air toward the right field for the smell.

To smell something, it must be of volatiles, in motion, or it must be brought to us with a matter that is in motion. When the smell gets in your particular area in the nose, it causes nerve power that travels to the brain, where we recognize the smell.
