Circulatory system( science)

  1. 1. Circulatory System<br />Circulation<br />Heart structure<br />
  2. 2. Circulation<br />
  3. 3. Function:<br /><ul><li>To transport materials</li></ul> around the body<br /><ul><li> Oxygen
  4. 4. Carbon dioxide
  5. 5. Digested food
  6. 6. Hormones
  7. 7. Waste chemicals - urea</li></ul> Heat <br />
  8. 8. 3 Major Parts of the Circulatory system<br /><ul><li>Blood Vessels- routes blood travels
  9. 9. Heart– pumps or pushes blood through body
  10. 10. Blood– carries important “ *stuff ” through body</li></ul>* Stuff – includes oxygen, food, & waste<br />
  11. 11.
  12. 12. 1 Blood Vessels: One Way Streets<br /><ul><li>Blood Vesselsresemble very long and skinny tunnels that are all through your body.</li></li></ul><li><ul><li>#2 The Heart</li></ul>4 chambers ( or compartments )<br />2 upper chambers : Left Atrium Right Atrium<br />2 lower chambers : Left Ventricle<br /> Right Ventricle<br />
  13. 13. <ul><li>#2 The Heart</li></ul>4 chambers ( or compartments )<br />2 upper chambers : Left Atrium Right Atrium<br />2 lower chambers : Left Ventricle<br /> Right Ventricle<br />

  15. 15. Lub <br />Dub<br />If you listen to your heartbeat, it makes a lub dub sound.<br />The lub is when blood is pushed out of the heart into the body and the dub is the reloading of the heart with more blood ready to push it out to the body<br />
  16. 16. Double Circulation<br />Left side <br />Oxygenated blood from the lungs enters the heart and is pumped to the body organs and tissues<br />Right side<br />Deoxygenated blood from the body is returned to the heart to be pumped to the lungs<br />
  17. 17. Blood Flow through the Human Body<br />Blood with little oxygen is pumped from the Right Atrium through a valve to the Right Ventricle and through another valve into the Pulmonary Vein. The Pulmonary Vein sends it to the Lungs to pick up Oxygen. It’s sent from the Lungs through Pulmonary Arteries to the Left Atrium through a valve to the Left Ventricle. The Left Ventricle sends it through a valve to the Aorta. The Aorta is a series of branches that sends oxygenated blood throughout the body.<br />
  18. 18. Pulmonary system – up to the lungs<br />CARBON DIOXIDE<br />OXYGEN<br />Systemic – to the organs of the body<br />
  19. 19. <ul><li>Heart Rate can be determined using a Stethoscope</li></li></ul><li>Your Blood is made of<br /><ul><li>Plasma
  20. 20. Liquid part of blood
  21. 21. Red Blood Cells</li></ul>They carry oxygen to all parts of the body<br />
  22. 22. <ul><li>White Blood Cells
  23. 23. Fight and kill germs that may enter your bloodstream</li></li></ul><li><ul><li>Platelets
  24. 24. Form “scabs” when you cut yourself
  25. 25. Helps stop the bleeding </li></li></ul><li>BLOOD TYPE<br />The ABO blood groups are the features most people know about.<br />In this group, there are 4 different types of red blood cells -- A, B, AB, and O.<br />
  26. 26. If someone is in an accident, has surgery or gets cancer, they may need another person’s blood to help them survive. <br />There is no substitute for blood transfusion. <br />This blood comes from blood donors.<br />
  27. 27. It is quick and it is safe.<br />It doesn’t hurt badly at all.<br />And it saves lives.<br />DONATING BLOOD <br />
  28. 28. BLOOD FACT<br />About half of world population who are above 18 years can safely be blood donors.<br />But only about 5 percent actually donate blood. <br />The other 95% are relying on these donors if they ever need a transfusion.<br />
  29. 29. EVALUATION<br />FILL IN THE BLANKS<br />In mammals, the ……………………………. Is divided into four parts.<br />The heart …………………………. Continuously .<br />The vessels carrying blood from the heart to the different parts of the body are called ………………………………………… <br />The vessels carrying blood from the parts of the body to the heart are called ………………………………….<br />
  30. 30. FILL IN THE RIGHT WORDS USING THE CLUES.<br />1)BLOOD <br />Route bloods travels<br />and <br />Voice maid by heart<br />3)<br />Pumps or pushes blood through body <br />GIVE REASONS <br />The walls of capillaries are thin.<br />2) It is necessary to match blood groups before giving a transfusion.<br />
