Sense Of Smell

Then you get a sense of smoke that comes up your nose and see that the oven is on fire and try to put it with a fire extinguisher but you can't so you get out and you are alive.

How you smell

You smell by your repector cells triggering each smell and that it what triggers the smell. Your nose breaths in the air and that is what activates the repector cells. Inside your nose is the olfactory epithelium which means smell device. In the smell device there are more than 10 million scent receptors These receptors can distinguish up to 10,000 different smells. Tiny odor molecules pass through the nose. The receptors send messages to the brain about the smells.
