  1. Aim: How is blood differentiated? HW: Blood Typing regents questions p.603 #1-13

  2. The breaking apart of platelets in the blood helps in the • synthesis of hemoglobin • formation of a clot • release of antibodies • deamination of amino acids

  3. Which body structures have walls one cell thick? • veins and arteries • trachea and bronchi • capillaries and alveoli • lymph vessels and stomach

  4. Which two systems are most directly involved in providing molecules needed for the synthesis of fats in human cells? • digestive and circulatory • excretory and digestive • immune and muscular • reproductive and circulatory

  5. The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies.

  6. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. A foreign substance that causes the body to produce antibodies What your body produces to protect “your body” Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.

  7. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.

  8. According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null). AB0 blood grouping system

  9. Blood group AA antigens on the surface of your red blood cells and B antibodies in blood plasma. Blood group BB antigens on the surface of your red blood cells and A antibodies in blood plasma.

  10. Blood group ABboth A and B antigens on the surface of your red blood cells and no A or B antibodies in blood plasma. Blood group 0neither A or B antigens on the surface of your red blood cells but both A and B antibodies in blood plasma.

  11. Rh factor • An antigen (Protein) on the red blood cell's surface. • Rh+ you have this protein on surface of blood cells • Rh- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). A person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ blood, whose Rh antigens can trigger the production of Rh antibodies. A person with Rh+ blood can receive blood from a person with Rh- blood without any problems.
