  2. R.B.C • Red blood cellscontain a special protein called hemoglobin, which contains iron and carries theoxygen to the body • Hemoglobin alsomakes red blood cells red. • We have so many red cells that our blood itself appears red, even though it contains more than red blood cells.

  3. Inheritance of Blood Types

  4. Discovery of Blood Typing • First to discover blood types (1900) Dr. Karl Landsteiner • Observed blood transfusions: the transfer of blood from one to another. • Noticed that the blood of the donor would clump/clot with that of the patient (Agglutination)

  5. The Four Classic Blood Types ____ ____ ____ ____ A B AB O The difference in blood types is caused by different proteins found of the surface of the red blood cells known as Antigen A and Antigen B.

  6. The Four Classic Blood Types Antigen _________:substance that can trigger the production of antibodies. Antibodies _____________:proteins produced by the immune system that destroy foreign substances (such as antigens).

  8. Rh Factor in Blood • The Rh factor is another protein factor on the Red Blood Cells • The term Rh comes from the type of monkeys used to test for this factor originally, Rhesus Monkeys

  9. Rh Factor Statistics • 85% of people have Rh present on their red blood cells. Their blood is referred to as _____ and they can receive ___________ blood. Rh+ + and - • 15% of people DO NOT have Rh present on their red blood cells. Their blood is referred to as ______ and they can receive ____________. Rh- only - O- • Universal blood donor (used by all)_____. • Universal blood recipient (can receive all types)____. AB+
