chapter 13 Flashcards
basophils (0-1)
respond to allergens, releases histamine and heparin
eosinophil (1-4)
responds to parasitic infections, phagocyte in allergic reactions
neutrophil (50-70)
major role in fighting bacterial infection, phagocyte
lymphocyte (20-40)
controls immune response, makes antibodies to antigens
monocyte (3-8)
phagocytic cell that becomes macrophage and digests bacteria and tissue debris

hypochromia
cells have reduced color (less hemoglobin)
macrocytosis
cells are large
microcytosis
cells are small
poikilocytosis
cells are irregularly shaped
spherocytosis
cells are spherical (loss of normal concave shape)
anemia
deficiency in erythrocytes or hemoglobin
aplastic anemia
failure of blood cell production in bone marrow
hemolytic anemia
reduction in red cells due to excessive destruction
sickle cell anemia
hereditary disorder of abnormal hemoglobin producing sickle shaped erythrocytes and hemolysis
thalassemia
inherited disorder of abnormal hemoglobin production leading to hypochromia
pernicious anemia
lack of mature erythrocytes caused by inability to absorb vitamin b12 into blood
hemochromatosis
excess iron deposits throughout body
polycythemia vera
general increase in rbc (erythremia)
hemophilia
excessive bleeding caused by hereditary lack of factors VIII or IX necessary for blood clotting
purpura
multiple pinpoint hemorrhages and accumulation of blood under skin
leukemia
increase in malignant white blood cells (leukocytes)
granulocytosis
abnormal increase in granulocytes in blood
mononucleosis
infectious, viral disease marked by increased numbers of mononuclear leukocytes and enlarged cervical lymph nodes
multiple myeloma
malignant neoplasm of bone marrow
antiglobulin (coombs) test
test for presence of antibodies that coat and damage erythrocytes
complete blood count (cbc)
determination of numbers of blood cells, hemoglobin conc, hematocrit, and red cell values
erythrocyte sedimentation rate (esr)
speed at which erythrocytes settle out of plasma
hematocrit (hct)
percentage of erythrocytes in volume of blood
hemoglobin test (H, Hg, Hgb, HGB)
total amount of hemoglobin in sample of peripheral blood
platelet count
number of platelets per cubic millimeter (mm3) or microliter of blood
prothrombin time (pt)
test of ability of blood to clot
red blood cell count (rbc)
number of erythrocytes per mm3 or microliter of blood
red blood cell morphology
microscopic examination of stained blood smear to determine shape of individual red cells
white blood cell count (wbc)
number of leukocytes per mm3 or microliter of blood
white blood cell differential [count]
percentages of diff types of leukocytes in blood
apheresis
separation of blood into component parts and removal of select portion from the blood
blood transfusion
whole blood or cells are taken from a donor and infused into a patient
bone marrow biopsy
microscopic examination of core of bone marrow removed with a needle
hematopoietic stem cell transplantation
peripheral stem cells from a compatible donor are administered to a recipient
