How the Nose is able to distinguish between a bad Odour and a good smell?
Your nose has the astonishing ability to smell thousands of different scents because in your nose are millions of smell receptors – cells that can recognize odor molecules. When you sniff the air, these special cells are alerted. These receptor cells then send a signal to your brain.
Can odors be detected?
Humans detect smells by inhaling air that contains odor molecules, which then bind to receptors inside the nose, relaying messages to the brain. Most scents are composed of many odorants; a whiff of chocolate, for example, is made up of hundreds of different odor molecules.
