  1. Rollin’ with the Flow The Cardiovascular System

  2. What does it do? • _______________________________________________________________________________________________________________ • Carries _______________ to and from all of the cells of the body. • Carries _______________ away from all of the cells of the body for expulsion.

  3. What makes the system work? • The __________________________________ • The pump that makes the entire system work • Made up of ____________

  4. How Many Chambers • 2 Upper—______________ • 2 Lower—_______________ • To test yourself on the heart’s anatomy, see: http://www.gwc.maricopa.edu/class/bio202/cyberheart/hartint0.htm

  5. Atria • Receives blood from the _________________ and sends it to the ventricles to be sent to the body • Smaller chambers • Pumps blood to the ___________

  6. Right Atrium • Receives _____________________ blood from the body through the vena cava • Pumps that blood to the right ventricle through the __________________ valve • The natural _____________ (for more on the body’s electrical system check out: http://science.howstuffworks.com/environmental/life/human-biology/heart4.htm

  7. Left Atrium • Receives ____________________ blood from the lungs through the pulmonary vein • Pumps oxygenated blood to the left ventricle through the ____________________ or Mitral valve

  8. Ventricles • Larger, stronger chambers • Sends blood to the body

  9. Right Ventricle • Receives ______________ blood from the _____________through the _________________ valve • Pumps that blood to the ________ through the __________________ valve to release _____ and pick up _______.

  10. Left Ventricle • Receives _______________blood from the left atrium through the Bicuspid or Mitral valve • Pumps that blood to the body through the _______________ and into the ______________ • Largest and strongest chamber

  11. Circulation

  12. Circulation

  13. Flows Away from the Heart • ________________________ • Generally speaking, arteries carry ___________________blood to the body--- __________ from the heart to the cells of the body • The exception is the _____________ artery which carries unoxygenated blood away from the heart to the lungs

  14. The LARGEST Artery • ____________________ • Largest artery in the body • Attached to the left ventricle where it receives the oxygenated blood and disperses it throughout the body

  15. Flow TO the Heart • _____________________ • Generally speaking, veins are vessels that carry ______________________________blood back to the heart • The exception is the _________________________vein which carries oxygenated blood back to the heart from the lungs

  16. The LARGEST Vein • __________________—attached to the right atrium • Superior-collects unoxygenated blood from the ______________ body • Inferior-collects unoxygenated blood from the ________________________ body

  17. Smaller • ___________________—smaller arteries that carry blood away from the heart to the cells • ___________________—smaller veins that carry blood to the heart away from the cells

  18. smaller yet • __________________ • Smallest vessels that carry blood between arterioles and venules • ______________________________________________________________________________________________ • “Where ___________________ does his work”

  19. BLOOD • Let’s watch a video on your blood: http://player.discoveryeducation.com/index.cfm?guidAssetId=49C615DC-8872-4CD7-A0BA-5840A0F09367 • Transporting substance in the body • Delivers O2, hormones, and nutrients to cells • Carries wastes including CO2 away from cells—to kidneys and lungs for expulsion • Check Teen Health for Blood info related to you….a teenager!! http://kidshealth.org/teen/your_body/body_basics/blood.html

  20. Blood

  21. Blood’s Make-up • _____________________________________ • Fluid in which the other parts of the blood are suspended • Contains __________________________________________________________________________________ • Made up of mostly ________________---90%

  22. Blood’s Make-up • Red Blood Cells • Transport O2 to the cells and tissues of the body • _____________________—O2-carrying protein in blood that also carries CO2 from the cells to the lungs for release

  23. Blood’s Make-up • White Blood Cells • __________________________________________________________________________________

  24. Blood’s Make-up • Platelets • __________________________________________________________________________________ • Sticky and ___________-forming
