We just learned about the Vomeronasal Organ.
Another part of the nose is the Olfactory Mucosa.
This is the wet skin on the inside of the nose that helps collect the things in the air that make smells.
The mucosa is like the inside of your mouth, and is wet and slimy.
Those smells stick to the wet slimy skin, and then some other sensors in the nose work to figure out what the smell is.
