1. RESPIRATORY SYSTEM How does it work?

2. Take in a big breath  Observe what happens when you breathe.  What movement did you notice?  Which system is responsible for movement?

3. Diaphragm  A dome shaped muscle beneath the lungs  Controls breathing  Contracts (pushes down) to expand chest cavity, which causes inhaling StructureFunction

4. What’s the difference?  Inhaling and exhaling of air  The process by which the body gets and uses oxygen and releases carbon dioxide and water BreathingRespiration

5. What’s the difference?  Primary respiratory organs that filter oxygen out of the air that we breathe in  Spongy, saclike organs  Filter dissolved oxygen from water for aquatic animals like fish LungsGills

6. Inhaling Airway  Nose – main passage way into the respiratory system  Pharynx – back of the throat, connects to larynx  Larynx – part of the throat that contains the vocal cords and guards the trachea  Trachea – Windpipe. Tube that connects the larynx to the lungs  Bronchi (bronchus) – Trachea splits in two branches, each one going to a lung  Bronchioles – Each bronchus divides into many smaller branches to all of the alveoli

7. How is a lung like a tree?  Draw a tree. What do you draw first?  Then what?  What do you add last?  Turn your drawing upside down…. resembles a lung

8. Alveoli  Tiny air sacs in the lungs  Walls are one cell thick  Sacs are covered with capillaries  Oxygen is passed into the blood stream to red blood cells  Carbon Dioxide is passed from red blood cells into the alveoli

9. Exhaling Airway  Reverse of Inhaling  Diaphragm relaxes (pushes up) to make chest cavity smaller  Carbon dioxide leaves alveoli into bronchioles (branches), through bronchi (trunk), up trachea (windpipe), through larynx, pharynx and exits out of the body out of the nose.

11. Why does our body need oxygen?  Cellular Respiration – Oxygen is used by the cells in the body to release energy  Cells use oxygen to release chemical energy  The byproducts of this process is carbon dioxide and water.

12. Why Cardiovascular System is helpful to Respiratory System  Blood leaving the lungs is oxygen-rich.  Pulmonary veins are carrying oxygen-rich blood to the heart to be pumped to the body.  In capillaries surrounding every cell, red blood cells deliver the oxygen.  As the RBC’s get rid of the oxygen, they pick up the waste (carbon dioxide)  Veins carry the oxygen poor blood back to the heart where it is pumped to the lungs.  Pulmonary Arteries carry oxygen-poor blood to the lungs. Carries and Delivers OxygenPicks up Waste

13. How is the AZ mail system like the cardiovascular & respiratory systems? AZ Mail system Comparison

14. Incoming mail  Have you ever had a pen-pal?  How do their letters get to you?  What about if letters are coming from out of state or out of the country?  How do you get the letters?  Once they get into AZ, how do the letters make it to your house?  http://viewpure.com/bB7dhE_TW9g http://viewpure.com/bB7dhE_TW9g

16. RESPIRATORY/ CARDIOVASCULAR SYSTEMS FLOW MAP How do these systems work together?

17. Your Assignment  Create a flow map that shows how the cardiovascular and respiratory systems work together.  Write in complete sentences and use correct punctuation.  The map should sequence the process of these systems. Start with the diaphragm contracting. Remember to write the words first, then draw the box.  At the end, be sure to include a frame of reference. Write a title at the top. References should be written on the outside of the frame and should include all the sources you used to get the information that is included in the map.

18. Be Specific!  Incorrect!  The cardiovascular and respiratory system work together including airway, lungs, blood vessels, heart, and the body.  Write the words first.  The diaphragm contracts, or pushes down, to allow the lungs room to expand and take in air.

19. The diaphragm contracts, or pushes down, to allow the lungs room to expand and inhale or take in air. Then draw the box and continue. Air comes in through the airway, which consists of the nose, pharynx, larynx, trachea, and bronchi.
