Blood Cell Components Flashcards
(42 cards)
Erythrocytes normal count
4.2-6.2 million erythrocytes/mm3
primary responsibility for erythrocyctes
Tissue oxygenation
Difference in RBC among men and women %
men 48%
women 42%
5 kinds of Leukocytes
neutrophils lymphocyctes monocytes eosinophils basophils
what are the 2 categories of leukocytes
granulocytes
aranulocyctes
3 kinds of granulocytes
neutrophils (50-67%)
eosinophils 0-3%
basophils 0-2%
2 kinds of aranulocytes
lymphocytes 24-40%
monocytes/macrophages 4-9%
4 characteristics of neutrophils
First to arrive at site of inflammation
Bands andsegs
Increase with acute bacterial infections and trauma
Shift to the left (increase of bands)
2 characteristics of lymphocyctes
Primary cells of immune response
Increase with chronic bacterial infection and acute viralinfection
2 characteristics of monocytes
Phagocytosis
Increase with bacterial infections & cancers
2 characteristics of Eosinophils
Increase with allergic reactions or parasiticinfections
Worms, wheezes, and weird diseases
Basophils characteristics
Increase with allergic reactions (hypersensitivities, inflammatory reactions)
What is hemoglobin Hgb
Measures amount of hemoglobin in your blood (oxygen carrying capacity
normals for Hgb
Men 13.5-17.5g/dL
Women 12-15.5 g/dL
cause for low Hgb
bleeding, folate/B12 deficiencies, cancers, kidney & liver disease
cause for high Hgb
polycythemia, COPD, high altitude, heavy smoking
What is Hematocrit Hct
Percentage of blood that is made up of packed red blood cells (RBCs
Interpreted in percentages
A hematocrit of 40% indicates that there are 40mL of packed RBCs in 100ml of blood
Hct normal levels
Male: 41-50%
Female: 36-44%
low Hct
anemia, bleeding, bleeding disorders, FLUID IMBALANCES
high Hct
polycythemia, COPD, dehydration, shock, congenital heard disease
red cell count
- # of erythrocytes in the blood
mean corpuscle volumve MCV
size of erythrocytes
Mean corpuscle hemoglobin (MCH
amount of hemoglobin in erythrocyte by weight
WBC Total Count
5,000-10,000/mm3 Increased= leukocytosis Decreased= leukopenia Decreased neutrophils= neutropenia Total counts degree of response to a pathological process
