What is the Respiratory System?
One of the most important body systems. The Respiratory System's main function is to breathe, or take in oxygen to help our body & cells function properly.
Breathing
How does breathing work? It's really simple......
-Lungs: Your lungs are surrounded by a rib cage, and rest upon the diaphragm. When you inhale, your diaphragm moves downwards and your rib cage expands.
1. You breathe through your nose or mouth. The oxygen then goes down your windpipe, also known as the trachea.
2. The air arrives at the lungs, and travels down smaller passages in the lungs called bronchial tubes.
3. The oxygen gets to the alveoli (tiny sacs surrounded by capillaries), and goes into the blood through the thin walls of the capillaries (and alveoli).
4. Finally, this whole process is complete when your exhale CO2 from your body!
