  9. Embolus
    A blood clot or other substance (bubble of air) that is moving in the blood and may block a blood vessel.
  10. Eosinophil
    WBC that is readily stained by eosin.
  11. Erythroblastosis Fetalis
    A disease that may develop when an Rh-negitive mother has anti-Rh antibodies and gives birth to an Rh-positive baby and the antibodies react with the Rh-positive cells of the baby
  12. Erythrocytes
    Red Blood Cells (RBCs)
  13. Fibrin
    Insoluble protein in clotting blood

    Volume % of blood cells in whole blood
  16. Hemoglobin
    Iron-containing protein in RBCs
  17. Hemorrhagic Anemia
    Condition characterized by low oxygen-carrying capacity of blood.

    Caused by decreased RBCs lifespan and/or increased rate of RBC destruction
  18. Heparin
    Substance obtained from the liver

    Inhibits blood clotting
