Chap 13, Blood System, Terminology Flashcards
basophil
White blood cell (leukocyte) containing dark granules that stain with a basic dye. The suffix -phil means attraction to.
hypochromic
Pert. to a deficiency in colour; decrease in hemoglobin in red blood cells. Hypochromic anemia is marked by a decreased concentration of hemoglobin in red blood cells.
anticoagulant
Substance that prevents blood clotting.
coagulopathy
Disease of blood clotting.
cytology
Study of cells.
eosinophil
A granular white blood cell with cytoplasmic granules that stain with eosin (a reddish dye).
erythroblast
Immature, developing red blood cell. (-blast means immature).
granulocyte
White blood cell with numerous dark-staining granules;eosinophil, neutrophil, and basophil.
hemolysis
Destruction of red blood cells. Destruction or breakdown of red blood cells. See hemolytic anemia.
hematocrit
Percentage of red blood cells in a given volume of blood. The suffix -crit means to separate. The hematocrit gives the percentage of RBCs in a volume of blood.
hemoglobinopathy
Disease or defect of hemoglobin production. Sickle cell anemia is an example.
anisocytosis
Inequality in the size of red blood cells. An abnormality of red blood cells; they are of unequal (anis/o) size; -cytosis means an increase in the number of cells.
magakaryocyte
Large, giant cell with a big nucleus; platelet precursor found in the bone marrow.
leukopenia
Deficiency of white blood cells.
monocyte
White blood cell with one large nucleus; capable of killing foreign substances by phagocytosis (ingestion). The cell has a single, rather than a multilobed, nucleus.
morphology
Study of the shape or form of cells.
myeloblast
Immature granulocytic white blood cell; a cell normally only found in the bone marrow. The suffix -blast indicates an immature cell.
myelodysplasia
Abnormal (ineffective) production of myeloid cells in bone marrow. (-plasia means development, formation, growth; increased # of cell growth). This is a preleukemic condition.
neutropenia
Deficiency in neutrophils. This term refers to neutrophils.
