| 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 |
