How your Lungs Work

Medically reviewed by Last updated on Apr 2, 2024.

What do I need to know about my lungs?

Your lungs are part of the respiratory system. The respiratory system contains organs and tissues that help you breathe. When you breathe in (inhale), your lungs remove oxygen from the air. The oxygen is moved into your blood and goes into your heart. Your heart then pumps the oxygen to the rest of your body. When you breathe out (exhale), your lungs remove waste gas (carbon dioxide) from your body.
