  1. Blood compatibility

  2. Blood types A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells

  3. Blood types There are four major blood types: A, B, AB, and O

  4. Antigens There are two antigens, A and B. If you have the A antigen on the RBC, then you have type A blood. When B antigen is present, you have type B blood.

  5. Antigens When both A and B antigens are present, you have type AB blood. When neither are present, you have type O blood.

  6. Rh blood group In addition to the ABO blood group system, there is an Rh blood group system The D antigen is the most common Rh antigen. If the D antigen is present, then that blood is Rh+. If the D antigen is missing, then the blood is Rh-.

  7. Blood compatibility Not all blood types are compatible There are universal donors and universal recipients

  8. In terms of RBC O- (universal donor blood) AB + (universal recipient) In terms of plasma Plasma extracted from type AB blood can be transfused to individuals of any blood group, but type O plasma can be used only by type O recipients

  10. The Circulatory System • Moves nutrients, gases, and wastes to and from cells • Helps fight diseases • Stabilizes body temperature and pH • Humans have a closed system (blood never leaves the network of arteries, veins, and capillaries

  11. The Circulatory System The circulatory system consists of : • The heart • Blood vessels • Blood

  12. The Circulatory System • Includes pulmonary circulation- oxygen depleted blood carried away from heart to lungs and returns oxygenated blood to heart • Systemic circulation- carries oxygenated blood away from heart to rest of body and returns deoxygenated blood

  13. The Arteries, Veins, and Heart • Arteries take blood away from the heart • Veins bring blood back to the heart • The heart has four chambers- left atrium, left ventricle, right atrium, right ventricle
