We have a special part in our nose that helps us know what things smell like. When you sniff something, tiny receptors inside your nose catch the scent and send messages to your brain so you can tell what it is. It's like having a secret detective team working all day to help you recognize smells.
Examples
- When you smell your favorite food, your nose detects the scent molecules that travel through the air.
- Your mom can tell when you’re sick just by the change in your smell.
- The reason you love fresh bread is because your brain recognizes the aroma of toasty wheat.
