Random Human Body Fact

Your nose has special receptors that are sensitive to odor molecules travelling through the air. These receptors are very tiny, and there are about 10 million of them in your nose! There are hundreds of different receptors, and each one can sense certain odors. These signals are then sent to the brain, which puts the signals together and tells you what you are smelling. The brain, working with the nose, can recognize over 10,000 different smells! (Human Body > The Nose )
