Humans have two nostrils because it helps them breathe better and smell things more clearly. Imagine trying to eat a whole pizza with just one mouth, you'd probably be really messy! Having two nostrils is like having two mouths for breathing, and they work together to help you catch smells from all around you.
Examples
- A person with one blocked nostril might snort more when they breathe.
- If you smell a cookie on the table, it feels stronger if both your nostrils are open.
