  4. 4. Blood [Formed elements]  Erythrocytes Red Cells - RBC  Leukocytes White Cells - WBC  Platelets
  5. 5. Blood at a Glance: Functions Transports substances throughout body  Substances are attached to red blood cells or dissolved in plasma White blood cells fight infection and disease Platelets initiate blood clotting process

  10. 10. Anatomy and Physiology Average adult has about five liters of blood Circulates through body within blood vessels Blood cells are produced in red bone marrow  Process called hematopoiesis
  11. 11. Anatomy and Physiology Is a mixture of cells floating in a fluid Fluid is plasma Cells are called formed elements  Erythrocytes (RBC)  Leukocytes (WBC)  Platelets
  12. 12. lymphocytesComponents of blood.
  13. 13. Plasma About 55% of whole blood Plasma is 90–92% water Remaining 8–10% is dissolved substances
  14. 14. Dissolved Substances in Plasma Plasma proteins  Albumin – helps transport fatty substances  Globulin – gamma globulins are antibodies  Fibrinogen – blood clotting protein Additional important substances  Calcium, potassium, sodium, glucose, amino acids, fats, urea, creatinine
  15. 15. leukocytesComponents of blood.
  16. 16. Red Blood Cells (RBC) Called erythrocytes Enucleated  No nucleus Biconcave disk 5 million per cubic millimeter of blood Adult has 35 trillion; more in males
  17. 17. Erythrocytes (RBC) Hemoglobin (Hgb, Hb) gives red color  Pigment containing iron  Responsible for oxygen transport Life span of 120 days  Spleen removes worn out ones  Iron can be reused  Bilirubin is waste product disposed of by liver http://upload.wikimedia.org/wikipedia/commons/1/19/Hemoglobin.jpg
  18. 18. White Blood Cells (WBC) Also called leukocytes Spherical shape with large nucleus 8,000 per cubic millimeter of blood
  19. 19. WBC - Leukocytes Provide protection against pathogens  Bacteria  Viruses  Foreign material Subdivided into two categories  Granulocytes – have granules in cytoplasm  Agranulocytes – no granules in cytoplasm
  20. 20. WBC - Leukocyte Classification Granulocytes  Basophils Release histamine and heparin to damaged tissue  Eosinophils Destroy parasites and increase during allergic reaction  Neutrophils Important for phagocytosis, engulf and destroy bacteria Agranulocytes  Monocytes Important for phagocytosis  Lymphocytes Provide protection through immunity, destroys viruses and produces antibodies
  21. 21. luekoocytesComponents of blood.
  22. 22. Platelets Also called thrombocyte Smallest of all blood elements Plate-like fragments of larger cell 200,000-300,000 per cubic millimeter … that means they are very, very small !!
  23. 23. Platelets Critical in blood clotting  Hemostasis Agglutinate into small clusters when blood vessel is damaged Leads to formation of thrombin (enzyme proteins catalyst)  Which converts fibrinogen, (plasma protein) from the liver to form the fibrin protein  Results in formation of mesh like blood clot
  24. 24. luekoocytesComponents of blood.
  25. 25. Blood Types Blood is made of the same basic elements, Not all blood is alike… In fact, there are .. 8 common blood types, which are determined by the presence or absence of certain antigens… substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patients immune system to attack the transfused blood, Safe blood transfusions depend on careful blood typing and cross-matching.
  26. 26. The ABO Blood Group SystemThere are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells:Group AHas only the A antigen on red cells (and B antibody in the plasma)Group BHas only the B antigen on red cells (and A antibody in the plasma)Group ABHas both A and B antigens on red cells (but neither A nor B antibody in the plasma)Group OHas neither A nor B antigens on red cells (but both A and B antibody are in the plasma)
  27. 27. Blood Typing Each person’s blood is different from others’  Due to presence of marker proteins on surface of erythrocytes Must do blood typing before blood transfusion  Test to determine if donated blood is compatible with recipient’s blood There are many different blood markers  Two most important ones for transfusions are ABO system and Rh factor
  28. 28. ABO System There are two possible RBC markers, A and B Person with A marker has type A blood  Type A blood produces anti-B antibodies  Anti-B antibodies attack type B and type AB blood Person with B marker has type B blood  Type B blood produces anti-A antibodies  Anti-A antibodies attack type A and type AB blood
  29. 29. ABO System Person with no marker has type O blood  Type O blood produces anti-A & anti-B antibodies  These antibodies will attack type A, type B, and type AB blood Person with both markers has type AB blood  Type AB blood produces no antibodies  Therefore it will not attack any other blood types

  32. 32. The ABO Blood Group SystemThere are very specific ways in which blood types must be matched for a safe transfusion: http://www.redcrossblood.org/learn-about-blood/blood-types
  33. 33. Rh Factor:a genetically determined protein on the red blood cells of some people that is one of the substances used to classify human blood as to compatibility for transfusion and that when present in a fetus but not in the mother causes a serious immunogenic reaction in which the mother produces antibodies that cross the placenta and attack the red blood cells of the fetus—called also
  34. 34. Rh Factor Person with Rh factor on red blood cells is Rh positive (Rh+) = present  Will not make anti Rh antibodies Person without Rh factor is Rh negative (Rh-) = absent  Will produce anti Rh antibodies Rh+ person may receive either Rh+ or Rh- transfusion Rh- person can receive only Rh- blood
  35. 35. Universal Donor Because type O blood does not have either marker A or B, it will not react with anti-A or anti-B antibodies found in other blood types For this reason a person with type O blood is referred to as a …. universal donor In an extreme emergency, type O blood may be given to a person with any other blood type
  36. 36. Universal Recipient Because a person with type AB blood has no antibodies against other blood types, it will not react with other blood For this reason, type AB blood is the universal recipient In an extreme emergency, a person with type AB blood may receive any type of blood
