  1. ObjectiveSeptember 20, 2011 • In our study of the respiratory system (R) the students will be able to identify (comprehension) functions and parts of the respiratory system and show what they learned by note-taking and drawing (evaluation)illustrations in their journal.

  2. Warm-Up • What do the words inhale and exhale describe when you breath?

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

  4. The system of the body that deals with breathing The body takes in the oxygen that it needs and removes the carbon dioxide that it doesn’t

  5. The Oxygen Delivery System • Main function - to supply the blood with oxygen • Does this through breathing

  6. Breathing and Respiration are NOT the same thing!

  7. Breathing Moving air in and out of the lungs

  8. 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.

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

  14. Pathway of Oxygen Capillary walls are so thin and close to each other that the air easily diffuses through.

  16. Pathway of Oxygen Oxygen diffuses through the capillaries into the bloodstream. Carbon dioxide in the bloodstream, diffuses through into the alveoli, and is then removed from the body when we breathe out.
