  1. RESPITATORY SYSTEM EVERY CHILD STRONGER EVERY LIFE LONGER!

  2. I'M BREATHING IN WHAT? • Although we can't see it, the air we breathe is made up of several gases. Oxygen is the most important for keeping us alive because body cells need it for energy and growth. Without oxygen, the body's cells would die. • Even if the air you breathe is dirty or polluted, your respiratory system filters out foreign matter and organisms that enter through the nose and mouth.

  3. DO I REALLY HAVE TO BREATHE?!? The respiratory system (or ventilatory system) is the biological system that introduces respiratory gases to the body and performs gas exchange.

  4. It's Not Just The Lungs • Nose/mouth • Trachea • Bronchi • Bronchioles • Alveoli

  5. Nose & Mouth In the Nose and Mouth- air is breathed in either or both. The air is then delivered down the Trachea (windpipe). Interesting facts only breathe through their nose!

  6. Bronchi & Bronchioles After the air travels down the Trachea, it will eventually either go left or right in the Bronchi- (the two main air passages) From the Bronchi- the air is divided into the Bronchioles, which are the even smaller air tubes (as thin as a strand of hair)

  7. Lungs and Alveolar Sacs Within the lungs are the tiny little sacs at the end of each Bronchiole called alveolar sacs or alveoli. The alveoli are where the exchange of oxygen and carbon dioxide takes place through diffusion.

  8. Once in the bloodstream, oxygen gets picked up by a molecule called hemoglobin (pronounced: hee-muh-glo-bun) in the red blood cells. This oxygen-rich blood then flows back to the heart, which pumps it through the arteries to oxygen-hungry tissues throughout the body.
