C:\Fakepath\Chemical Bonding

  1. 1. Chemical BondingPower point<br />By: Marissa Rooney<br />All pictures found at google.com<br />
  2. 2. Hemoglobin<br /><ul><li> Hemoglobin is the substance within your red blood cells that spreads oxygen to the lungs and the rest of your body.
  3. 3. Hemoglobin is the reason red blood cells appear red.
  4. 4. Hemoglobin is made in the bone marrow as needed.</li></li></ul><li>Why Hemoglobin and oxygen work together.<br /><ul><li> Hemoglobin is actually the reason red blood cells appear red, although oxygen-rich blood is noticeably brighter than the depleted blood returning to the heart and lungs.</li></li></ul><li>Why hemoglobin a real-life example.<br />Covalent bond<br /><ul><li> The transporting of hemoglobin by oxygen is a real-life example of chemical bonding because it relates to ionic and covalent bonding.</li></ul>Ionic bonding<br />
  5. 5. Give me more<br /><ul><li> The reason that more Hemoglobin is a key essential to climbing Mt. Everest is because the air is thinner than the air we breath.
  6. 6. The thin air is bad because the oxygen level will go done. Thus making it harder to make sound decisions which, in extreme cases, can make the diffrence of life and dealth.</li></li></ul><li>pH of Blood<br /><ul><li>pH has to do with the transport of hemoglobin because this is a protein- based substance which your blood needs to maintain a pH of 7.35 to 7.45 for your cells to function properly. </li></ul> The proteins that work in your body have to maintain a specific geometric shape to function, and the three-dimensional shapes of the proteins in your body are affected by the tiniest changes in the pH of your body fluids.<br />
  7. 7. Blood Doping<br /><ul><li>Blood doping involves harvesting an athlete's own blood before a competition or finding a matching blood donor.
  8. 8. This blood is usually processed in order to create a concentration of red blood cells, then frozen until needed for transfusion back into the athlete shortly before the event.
  9. 9. Blood doping is the process of artificially increasing the amount of red blood cells in the body in an attempt to improve athletic performance.</li></li></ul><li>Antilogous vs. Homologues blood doping<br /><ul><li> This blood is processed in order to create a concentration of red blood cells, then frozen until needed for transfusion back into the athlete shortly before the event.
  10. 10. Essentially an antilogous procedure is one where part of the person’s body, and this could be as tiny stem cells, are used as part of a procedure for that person. It is medicine’s way of using what the person has to address a medical need.</li></li></ul><li>EPO <br /><ul><li>Erythropoietin is a relatively recent entry into the deceitful pursuit of glory. EPO is a protein hormone produced by the kidney. After being released into the blood stream it binds with receptors in the bone marrow, where it stimulates the production of red blood cells (erythrocytes).
  11. 11. EPO has put a whole new spin on blood doping. No need for messy transfusions, just shoot up with EPO to increase your circulating erythrocyte mass.</li></li></ul><li>Medical uses of blood doping<br />This could save a persons life if they loose to much blood.<br />This helps athletes. <br />
  12. 12. Sports <br /><ul><li> Blood doping is used in sports because it increases the amount of blood flow thus increasing the amount of oxygen to the brain. The helps them keep going.</li></li></ul><li>Ex1<br />Pierre de Coubertin, founder of the modern Olympic games, was one of the first to point out the necessity of protecting sport from the dangers threatening it as an institution. In 1923, in a speech delivered in Rome, he denounced &quot;the intrusion of politics into sports, the increasingly venal attitude towards championship, the excessive worshipping of sport, which leads to a belief in the wrong values, chauvinism, brutality, overworking, overtraining, and doping&quot;. <br />http://www.cnrs.fr/cw/en/pres/compress/dopage/dopage2.html<br />
  13. 13. Ex2<br />The recent doping scandal of the last Tour de France cycling competition drew the attention of the media to practices which, until then, had remained covert. This media coverage has increased public awareness of this phenomenon. Indeed, due to their scope and sophistication, doping practices are a threat to more than just the world of sport. Though first considered to be no more than a cheating problem, the doping issue has reached such proportions that it now concerns society as a whole. As the stakes involved in sport grow higher and the phenomenon more widespread, the moral values attached to sport are increasingly called into question and the health of athletes increasingly at risk.<br />http://www.cnrs.fr/cw/en/pres/compress/dopage/dopage2.html<br />
  14. 14. Side effects<br />Blood doping is cheating and has several unhealthy side effects. Injecting blood doping chemicals can cause kidney damage, jaundice (the skin, eyes and body fluids turn yellow) and blood clots. Re-injecting blood from an athlete&apos;s own body can cause blood infections and heart problems. <br />
