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.


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!

Keep Your Lungs Healthy

How to keep your lung healthy???
You should exercise like running, basketball, and etc. And drink lots of water to keep it clean in your body!!!!

What harms the lung:
  • Smoking (other drugs)-clogs up your lungs and results in lung cancer
  • Poisonous Gas- It can harm your breath intake and when you inhale toxic fumes, you are basically eating poison

Fun Fact!- The average person breathes in about 11,000 liters of air everyday!!!
