The nose can smell a variety of smells because in the nasal cavity there are nerve fibers of the smelter consisting of millions of cells of the smell. Each of these aberrant cells has hairs on the ends and is covered with mucous membranes that serve to moisten the nasal cavity.
When we breathe, breathing air from the outside, the odor molecules that float in the air will come into the nasal cavity and meet the cells of the smell. The cells of the smell will be aroused and change the stimulus into a signal that then sends it to the brain through the nerve stalker. Thus we can smell various odors from the outside air.
