Transcript of "Human Circulatory System"

  1. 1. Circulatory System<br />
  2. 2. Circulatory System<br />Carries nutrients, oxygen and other substances to all the cells of the body<br />Carries away waste products<br />Distributes oxygen throughout the body<br />Contains 3 main parts<br />
  3. 3. Main Parts<br />Heart – acts like a pump moving blood throughout the body<br />Blood – made of many parts<br />Blood Vessels – consists of veins, arteries, and capillaries<br />
  4. 4. THE BLOOD<br />
  5. 5. Function of Blood<br />Transport oxygen and nutrients throughout the body<br />Carries waste materials to the lungs and kidneys<br />Regulates body temperature<br />Fights diseases<br />
  6. 6. Parts of Blood<br />Plasma<br />Red Blood Cells<br />Platelets<br />White Blood Cells<br />What do you already know?<br />
  7. 7.
  8. 8. Plasma<br />Platelets<br />White blood cells<br />Red blood cells<br />Whole Blood Sample<br />Sample Placed in Centrifuge<br />Blood Sample That Has Been Centrifuged<br />
  9. 9. Plasma<br />Platelets<br />White blood cells<br />Red blood cells<br />Whole Blood Sample<br />Sample Placed in Centrifuge<br />Blood Sample That Has Been Centrifuged<br />
  10. 10. Plasma<br />Platelets<br />White blood cells<br />Red blood cells<br />Whole Blood Sample<br />Sample Placed in Centrifuge<br />Blood Sample That Has Been Centrifuged<br />
  11. 11. Plasma<br />Liquid part of blood<br />Made of water and other molecules<br />Clear, yellowish liquid<br />
  12. 12. Carries dissolved nutrients to the cells of the body<br />Carries carbon dioxide and wastes away from the cells<br />Makes up about 55% of blood<br />
  13. 13. Red Blood Cells<br />Makes up about 44% of blood<br />Relatively small in size<br />Numerous in number<br />Cells are disk shaped with the center of each side pushed in<br />
  14. 14. Red Blood Cells Cont.<br />Carries oxygen molecules from the lungs to other parts of the body<br />Do not have a nucleus<br />Cannot reproduce<br />Get color from oxygen – carrying chemical called hemoglobin<br />
  15. 15.
  16. 16. Platelets<br />Small, colorless packets of cytoplasm<br />Causes blood to clot<br />Blood Clot: think about your scabs… and draw a picture of how this works.<br />
  17. 17.
  18. 18.
  19. 19. Notice how they form a trail – they stick together to any foreign surface!<br />
  20. 20. White Blood Cells<br />Relatively large<br />Few in number<br />Have a nucleus<br />Fights invading organisms by producing antibodies (FIGHTS GERMS!)<br />
  21. 21. http://en.wikipedia.org/wiki/White_blood_cell<br />Look at the table to view different kinds of white blood cells.<br />What are some of the things your white blood cells do for your body?<br />
  22. 22. Red vs. White Cells Real Player Video<br />
  23. 23. Blood Vessels<br />
  24. 24. 3 Major Types of Blood Vessels<br />Arteries – Blood vessels that carry blood away from the heart<br />Veins – blood vessels that carry blood to the heart<br />Capillaries – tiny blood vessels that connect arteries to vein<br />
  25. 25.
  26. 26. With each heartbeat, arteries carry about 20 to 25 percent of your blood to your brain, where billions of cells use about 20 percent of the oxygen and fuel your blood carries.<br />When you are thinking hard, your brain may use up to 50 percent of the fuel and oxygen.<br />

  31. 31. Arteries and Veins<br />Real Player Video Clip<br />
  32. 32. The Heart<br />
  33. 33. The Heart<br />Powerful, muscular pump<br />Maintains a continuous flow of blood around the body<br />Divided into 2 halves<br />Atrium: smaller, upper chamber<br />Ventricle: larger, lower chamber<br />

  41. 41. The Path of Blood<br />The heart pumps blood to the lungs<br />The blood gets oxygen in the lungs<br />The blood returns to the heart<br />The heart pumps the oxygenated blood to the cells in the body<br />The blood delivers oxygen to the body cells<br />The deoxygenated blood travels back to the heart<br />
