Medical Terminology OFT 140

  1. Microcytosis
    the presence of small red blood cells
  2. Macrocytosis
    the presence of large red blood cells
  3. Anisocytosis
    the presence of red blood cells of unequal size (an= without; iso= equal)
  4. Poikilocytosis
    the presence of large, irregularly shaped red blood cells (poikil/o= irregular)
  5. Reticulocytosis
    an increase of immature erythrocytes in the blood
  6. Erythropenia
    an abnormally reduced number of red blood cells
  7. Lymphocytopenia
    an abnormally reduced number of lymphocytes
  8. Neutropenia
    a decrease in the number of neutrophils
  9. Pancytopenia
    an abnormally reduced number of all cellular components in the blood
  10. Hemolysis
    breakdown of the red blood cell membrane
  11. Immunocompromised
    impaired immunological defenses caused by an immunodeficiency order or therapy with immunosupressive agents
  12. Immunosupression
    Impaired ability to provide an immune response
  13. Lymphadenopathy
    the presence of enlarged (diseased) lymph nodes
  14. Splenomegaly
    enlargement of the spleen
  15. Acquired Immunodeficiency Syndrome (AIDS)
    a syndrome caused by the human immunodeficiency virus (HIV) that renders immune cells ineffective, permitting opportunistic infections, malignancies, & neurological diseases to develop; it is transmitted sexually or through exposure to contaminated blood
  16. Anemia
    a condition in which there is a reduction in the number of red blood cells, the amount of hemoglobin, or the volume of packed red cells within the blood, resulting in the diminished ability of the red blood cells to transport oxygen to the tissue (3 common types= aplastic anemia, iron deficiency anemia, pernicious anemia)
  17. Aplastic Anemia
    a normocytic-normochromic type of anemia characterized by the failure of bone marrow to produce red blood cells
  18. Iron Deficiency Anemia
    a microcytic-hypochromic type of anemia characterized by a lack of iron, affecting production of hemoglobin & characterized by small red blood cells containing low amounts of hemoglobin
  19. Pernicious Anemia
    a macrocytic-normochromic type of anemia characterized by an inadequate supply of vitamin B12, causing red blood cells to become large, varied in shape, & reduced in number
  20. Autoimmune Disease
    any disorder characterized by the abnormal function of the immune system that caused the body to produce antibodies against itself, resulting in tissue destruction or loss of function (rheumatoid arthritis, lupus)
  21. Erythroblastosis Fetalis
    a disorder that results from the incompatibility of a fetus with an Rh-positive blood factor & a mother who is Rh-negative, causing red blood cell destruction in the fetus; necessitates a blood transfusion to save the fetus
  22. Rh Factor
    the presence, or lack, of antigens on the surface of red blood cells that may cause a reaction between the blood of a mother & fetus, resulting in fetal anemia
  23. Hemochromatosis
    a hereditary disorder that results in an excessive buildup of iron deposits in the body
  24. Hemophilia
    a group of hereditary bleeding disorders in which there is a defect in clotting factors necessary for the coagulation of blood
  25. Leukemia
    a chronic or acute malignant (cancerous) disease of the blood forming organs, marked by abnormal leukocytes in the blood & bone marrow; classified according to the white cells affected (myelocytic, lymphocytic, etc)
  26. Myelodysplasia
    a disorder within the bone marrow characterized by the proliferation of abnormal stem cells (cells that give rise to different types of blood cells); usually develops into a specific type of leukemia
  27. Metastasis
    the process by which cancer cells are spread by blood or lymph circulation to distant organs
  28. Mononucleosis
    a condition caused by the Epstein-Barr virus characterized by an increase in mononuclear cells (monocytes & lymphocytes) in the blood, along with enlarged lymph nodes (lymphadenopathy), fatigue, & sore throat (pharyngitis)
  29. Polycythemia
    an increase in the number of erythrocytes & hemoglobin in the blood
  30. Septicemia
    a systemic disease caused by the infection of microorganisms & their toxins in the circulating blood
  31. Thrombocytopenia
    a bleeding disorder characterized by an abnormal decrease in the number of platelets in the blood, which impairs the clotting process
