Blood compatibility

Learn about the four major blood types (A, B, AB, O), antigens, and the Rh blood group system. Discover blood compatibility, universal donors and recipients, and the importance of plasma. Explore the circulatory system's function, components (heart, vessels, blood), and pulmonary versus systemic circulation.

Presentation Transcript

  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
