Fichas del conjunto (54)
- 1Whole bloodis the blood composition that includes erythrocytes, leukocytes, platelets, & plasma
- 2Buffy coatis a small white layer of cells (leukocytes & platelets) lying between the packed red blood cells & the plasma)
- 3Plasmais the liquid portion of unclotted blood
- 4Serumis the fluid that remains after coagulation has occurred & a clot has formed
- 5a-without
- 6-blastyoungest/nucleated
- 7-chromiccolored
- 8-cytecell
- 9dys-abnormal
- 10-emiain the blood
- 11ferro-iron
- 12hyper-increased
- 13hypo-decreased
- 14iso-equal
- 15macro-large
- 16mega-very large/huge
- 17micro-small
- 18myelo-marrow
- 19normo-normal
- 20-oidlike
- 21-osisincreased
- 22pan-all
- 23-peniadecreased
- 24-plasiaformation
- 25-poiesiscell production
- 26poly-many
- 27pro-before
- 28thrombo-clot
- 29Homeostasisis the body's tendency to move toward physiological stability
- 30Osmotic concentrationis the body/cellular water concentration
- 31Isotonicis the normal osmotic concentration
- 32HypotonicWater enters the cell; the cell swells, & may lyse (greater amount of H2O in relationship to lesser amount of solutes)
- 33HypertonicWater leaves the cell; the cell may crenate (lesser amount of H2O in relationship to greater amount of solutes)
- 34MCVStands for mean corpuscular volume. It is an indicator of the average or mean volume of erythrocytes (RBCs) in femtoliters
- 35MCHStands for mean corpuscular hemoglobin. It is an indicator of the average weight of hemoglobin in individual RBCs in picograms
- 36MCHCStands for mean corpuscular hemoglobin concentration. It is a measure of the average concentration of hemoglobin in grams per deciliter
- 37RDWStands 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)
- 38AnisocytosisVariation in size
- 39HctStands for hematocrit. It is the percentage of RBCs in a given volume of whole blood
- 40HgbStands for hemoglobin. It is given in grams per deciliter. Hgb is age & sex dependent
- 41PLTStands for platelets. It is given in a number per microliter of blood
- 42Relative countIs the amount of a cell type in relation to other blood components
- 43Relative lymphocytosisis an increase in the percentage of lymphocytes; frequently associated with neutropenia.
- 44Relative polycythemiaRBCs appear increased due to a decreased plasma volume
- 45Absolute countis the actual number of each cell type without respect to other blood components.
- 46Absolute lymphocytosisis a true increase in the number of lymphocytes
- 47Absolute polycythemiais a true increased in red cell mass
- 48Continue from Success Review BookBottom of pg. 233 or beginning of pg. 234
- 49HematopoiesisProduction & differentiation of blood cells
- 50Cellularityis the ratio of marrow cells to fat (red marrow/yellow marrow)
- 51M:E (myeloid/erythroid) ratiois the ratio of granulocytes & their precursors to nucleated erythroid precursors
- 52Lymphoid? (Pg. 235)Includes progenitor cells that differentiate into either B or T lymphocytes in response to cytokines/lymphokines/interleukins/CSFs/growth factors
- 53Myeloid? (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
