Question Answer
length of time necessary to produce erythrocytes5 days
sites of RBC production within bone marrowerythroblastic islands
recommended stain got stinaing peripheral bloodWright stain
how many miles will an erythrocyte travel during its lifespan300 miles
what substance does not diffuse freely across cell membranesodium
embden-myerhoff pathwayprovides 90% of the cellular ATP necessary for anaerobic red cell metablism
preferred anticoagulant in hematologyEDTA
aged red cels are calledspherocytes
howell jolly body pathophysiologyDNA in origin
basophilic stippling is caused by whatdenatured remnants of mRNA
pappenheimer bodiesiron
heinz bodiesdenatured hemoglobin
basophilic stimppling is associated withlead posioning
integral proteinsstart from the cytoskeleton and expland throughout entire red cell membrane
polychromasiaincreased resence of reticulocytes in periperal blood, peripheral cell response to accelerated erythropoiesis
anaerobicwithout oxygen
cytoskeletonthe backbone/layer under the membrane of the cell that gives it structure
anistocytosisvariation in size of red cells
polkilocytosisvariation in shape of red cells
spherocytes are best descrubd as normal MCV with elevated MCHC
abnormal hemoglobin in sickle cellhemoglobin S
target cells can be associated with what condition?increased levels of hemoglobin
anaerobic metabolism accounts for what percentage of energy to the RBC90%
The majority of the energy for the erythrocyte is in what formanaerobic
when are fragmented red cells seen?heart disease, burns
when can ovalocytes be seensome types of anemia
when are eliptocytes seenIDA
howell-jolly bodies are often seen inerythrocytosis
target cells are associated withliver disease
MCHmean corpuscular hemoglobin- size and hgb
MCVmean corpuscular volume- represents cell size and volume
MCHCmean corpuscular hemoglobin concentration- hgb concentration in cell which determines color
RDWred cell distribution width- variation in size
differentialusing a smear to look at/ investigate the percentages of WBCs in the blood
