But here's how air moves in a human body:
1. Inhale: You breathe in air through your nose or mouth.
2. Trachea: The air travels down your windpipe (trachea).
3. Lungs: The trachea branches into two tubes that lead to your lungs.
4. Bronchi: The tubes further divide into smaller tubes called bronchi, which lead to tiny air sacs called alveoli.
5. Alveoli: This is where the magic happens! Oxygen from the air passes into tiny blood vessels surrounding the alveoli.
6. Bloodstream: The oxygen-rich blood travels throughout your body, delivering oxygen to all your cells.
7. Exhale: Carbon dioxide, a waste product from your cells, travels back to the lungs and is breathed out.
So, the air you breathe in gets used to deliver oxygen to your cells, and then the waste product (carbon dioxide) is exhaled. 😊
