  1. Hi, My name is Vanessa and this is my presentation on blood groups.
  2. The objectives for today are to be able to
  3. identify antigen and antibody constituents for each block group.
  4. Be able to distinguish the different donor compatibility is and the consequences
  5. of react Cross reaction finally understand the importance of Rh blood groups.
  6. We have four blood groups A, B, A, B and O.
  7. These are genetically determined by Mandela in inheritance.
  8. Each one has a specific combinations of antigens and antibodies.
  9. For example Oh is a universal donor because it has no oxygen.
  10. So it does not ignite an immune response in any other recipients.
  11. A B is a universal receptor because it has no antibodies to attack donor blood.
  12. Hey,
  13. my policies is the destruction of red
  14. blood cells that happens during cross reaction
  15. when incompatible blood mixes For example,
  16. a donor with blood group A her surface antigen A giving
  17. blood blood to a recipient with blood group being an antibody,
  18. eh?
  19. The recipient antibody a will attack the antigen a of the donor
  20. and this can be life threatening for the recipient.
  21. Next we have Rh Blood group
  22. are his blood group determines whether you're a
  23. B O blood group is positive or negative.
  24. Positive means you're anti.
  25. You have Auntie Jean de on the surface of your red
  26. blood cell and negative means Auntie Jean de is absent.
  27. Blood transfusion with D antigen blood to a patient with negative blood groups
  28. would cause him osmosis.
  29. This is why positive blood groups cannot donate a negative for the
  30. same reasons why blood group A cannot donate blood group B.
  31. But negative
  32. blood groups can donate to positive.
  33. This makes all minus the true universal donor
  34. and a B positive the true universal acceptance.
  35. I hope you've been able to learn something today.
  36. I have set up questions for you to answer.
  37. Pause the video to answer the question individually and
  38. skip to the end of the video for answers.
  39. Question one.
  40. A patient with blood Group A needs urgent blood
  41. transfusion and has three siblings willing to donate.
  42. Who can the patient receive blood from
  43. question two
  44. or antigen and antibody constituents? Does a patient with a B blood group have
  45. finally question three?
  46. What would happen if an Rh positive individual
  47. donate blood to the Rh negative partner?
  48. A. Nothing.
  49. Be hemolytic cross reaction and see an immune response.
  50. These are the answers. Thank you
