Your Lungs Can “Sniff” the Air
Your lungs don’t just breathe — they smell too!
- Specialized receptors in lung tissue can detect odor molecules, similar to your nose.
- This helps the lungs respond quickly to harmful substances, like smoke or chemicals, by triggering reflexes such as coughing or airway tightening.
Why it matters:
This built-in “smoke detector” is one reason secondhand smoke and pollution can cause an immediate reaction, even before your nose notices the smell.
