Questão | Responda |
Whole blood | is the blood composition that includes erythrocytes, leukocytes, platelets, & plasma |
Buffy coat | is a small white layer of cells (leukocytes & platelets) lying between the packed red blood cells & the plasma) |
Plasma | is the liquid portion of unclotted blood |
Serum | is the fluid that remains after coagulation has occurred & a clot has formed |
a- | without |
-blast | youngest/nucleated |
-chromic | colored |
-cyte | cell |
dys- | abnormal |
-emia | in the blood |
ferro- | iron |
hyper- | increased |
hypo- | decreased |
iso- | equal |
macro- | large |
mega- | very large/huge |
micro- | small |
myelo- | marrow |
normo- | normal |
-oid | like |
-osis | increased |
pan- | all |
-penia | decreased |
-plasia | formation |
-poiesis | cell production |
poly- | many |
pro- | before |
thrombo- | clot |
Homeostasis | is the body's tendency to move toward physiological stability |
Osmotic concentration | is the body/cellular water concentration |
Isotonic | is the normal osmotic concentration |
Hypotonic | Water enters the cell; the cell swells, & may lyse (greater amount of H2O in relationship to lesser amount of solutes) |
Hypertonic | Water leaves the cell; the cell may crenate (lesser amount of H2O in relationship to greater amount of solutes) |
MCV | Stands for mean corpuscular volume. It is an indicator of the average or mean volume of erythrocytes (RBCs) in femtoliters |
MCH | Stands for mean corpuscular hemoglobin. It is an indicator of the average weight of hemoglobin in individual RBCs in picograms |
MCHC | Stands for mean corpuscular hemoglobin concentration. It is a measure of the average concentration of hemoglobin in grams per deciliter |
RDW | Stands for RBC distribution width. It is a parameter that measures the variation in RBC size or RBC volume in percentage. RDW is elevated in accordance with variation in red cell size (anisocytosis) |
Anisocytosis | Variation in size |
Hct | Stands for hematocrit. It is the percentage of RBCs in a given volume of whole blood |
Hgb | Stands for hemoglobin. It is given in grams per deciliter. Hgb is age & sex dependent |
PLT | Stands for platelets. It is given in a number per microliter of blood |
Relative count | Is the amount of a cell type in relation to other blood components |
Relative lymphocytosis | is an increase in the percentage of lymphocytes; frequently associated with neutropenia. |
Relative polycythemia | RBCs appear increased due to a decreased plasma volume |
Absolute count | is the actual number of each cell type without respect to other blood components. |
Absolute lymphocytosis | is a true increase in the number of lymphocytes |
Absolute polycythemia | is a true increased in red cell mass |
Continue from Success Review Book | Bottom of pg. 233 or beginning of pg. 234 |
Hematopoiesis | Production & differentiation of blood cells |
Cellularity | is the ratio of marrow cells to fat (red marrow/yellow marrow) |
M:E (myeloid/erythroid) ratio | is the ratio of granulocytes & their precursors to nucleated erythroid precursors |
Lymphoid? (Pg. 235) | Includes progenitor cells that differentiate into either B or T lymphocytes in response to cytokines/lymphokines/interleukins/CSFs/growth factors |
Myeloid? (Pg. 235) | Includes progenitor cells that gives rise to the multipotential progenitor CFU-GEMM (colony-forming-unit-granulocyte-erythrocyte-macrophage-megakaryocyte),which will differentiate into committed progenitor cells & finally mature blood cells in response to cytokines/interleukins/colony stimulating factors/growth factors |
