  1. The Respiratory System http://137.222.110.150/calnet/irish_cal/exotics/respiratory%20system.jpg

  2. The system of the body that deals with breathing (gas exchange) The body takes in the oxygen that it needs and removes the carbon dioxide that it doesn’t

  3. The Oxygen Delivery System • Main function - to supply the blood with oxygen • Does this through breathing • Breathing and Respiration are NOT the same thing!

  4. Breathing vs. Respiration • Moving air in and out of lungs vs.

  5. Inhalation • Breathing in • Body gets oxygen from the air • Rib muscles contract to pull ribs up and out • Diaphragm muscle contracts to pull down the lungs • Tissue expands to force (pull) in air.

  6. Exhalation • Breathing out • Get rid of carbon dioxide • Rib muscles relax • Diaphragm muscle relaxes • Tissue returns to resting position and forces (pushes) air out

  7. Parts of the System • Mouth • Nose • Pharynx/ larynx • Trachea • splits into bronchi • bronchioles • Lungs • Bronchioles • Alveoli • Diaphragm

  9. Lung structure • Bronchial tubes • Many smaller tubes • Alveoli (alveolus) – surrounded by capillaries • Average adult's lungs contain about 600 million of these air-filled sacs
