hematocrit
|
percentage of total blood volume occupied by RBCs
normal in adult fms 38%-46% (42% avg) normal in adult ms 40%-54% (47% avg) |
|
hemoglobin
|
oxygen-carrying protein which is a pigment that gives blood its color
|
|
hematopoeisis
|
(hemopoeisis) process by which formed elements of blood develop
|
|
erythropoiesis
|
production of RBCs
|
|
platelet formation
|
(platelet plug) aggregation of platelets at a site where a blood vessel is damaged that helps stop or slow blood flow
|
|
hemocytoblast/hematocytoblast/pluripotent stem cell
|
these cells have the capacity to develop into different types of cells
|
|
leukopoiesis
|
production of WBCs
|
|
differential WBC count
|
"diff"
a count of each of the five types of white blood cells |
|
hemolysis
|
the rupture/destruction of RBCs
|
|
reticulocytes
|
cell near the end of erythropoeisis that has ejected the nucleus but retains some organelles; develops into mature RBCs in 1 to 2 days
|
|
erythropoietin
|
(EPO) hormone produced by kidney & increases the number of RBC precursors
|
|
blood doping
|
increasing RBC count to gain a competitive edge
|
|
hypoxia
|
cellular oxygen deficiency
|
|
antigen
|
substance with the ability to provoke an immune response & the ability to react with the antibodies or cells resulting from the immune response
|
|
antibody
|
protein produced by plasma cells in response to a specific antigen (combines with antigen to destroy it); immunoglobulin
|
|
HDN
|
hemolytic disease of the newborn
mother RH- and firstborn RH+, leaked RH from baby to mother causes mother to produce anti-RH, causes HDN when second baby is RH+ also |
|
agglutination
|
clumping of RBCs when antibodies bind to antigens in an incompatible blood transfusion
|
|
RH factor
|
RH antigen found in blood
|
|
polycythemia
|
RBCs percentage is abnormally high (may have hematocrit that is 65% or higher)
|
|
thalassemia
|
deficient hemoglobin synthesis
|
|
edema
|
buildup of fluid in tissues
|
|
anemia
|
condition where oxygen-carrying capacity of blood is reduced
|
|
sickle cell anemia
|
RBCs contain abnormal hemoglobin Hb-S, bending erythrocytes in a sickle shape
|
|
warfarin
|
anticoagulant acting as antagonist to vitamin K, blocking synthesis of four clotting factors
|
|
heparin
|
anticoagulant produced by mast cells and basophils, increases antithrombin effectiveness
|
|
venipuncture
|
withdrawal of blood from a vein using a needle and collecting tube
|
|
arterial puncture
|
blood is drawn from artery to determine the level of oxygen in oxygenated blood
|
|
leukemia
|
red bone marrow cancers where abnormal white blood cells multiply uncontrollably
|
|
hemophilia
|
inherited deficiency of clotting where bleeding may occur spontaneously or after only minor trauma
|
|
leukocytosis
|
WBC count above the normal range
|
|
leucopenia
|
decrease in WBC numbers in blood, causing susceptibility to disease
|
|
septicemia
|
"blood poisoning"
toxins or disease-causing bacteria in the blood |
|
jaundice
|
abnormal yellowish discoloration of the sclera of the eyes, skin, and mucous membranes due to excess bilirubin in blood
|
|
thrombocytopenia
|
very low platelet count that results in a tendency to bleed from capillaries
|
|
prostacyclin
|
a compound of the prostaglandin type that is produced in arterial walls
functions as an anticoagulant and vasodilator |
|
positive chemotaxis
|
movement towards higher concentrations of certain chemicals
|
