Med term: Ch12 blood Flashcards
agglutination
clumping of cells and particles in blood
aglutinogen
substance that causes agglutination
agranulocyte
leukocyte with nongranular cytoplasm
albumin
simple protein found in plasma
basophil
leukocyte containing heparin and histamine
blood
fluid (containing plasma, RBCs, WBCs, and platelets) circulated throughout the arteries, veins, capillaries, and heart
blood types or groups
classification of blood according to its antigen and antibody qualities
coagulation
changing of a liquid, especially blood, into a semi-solid
electrophoresis
process of separating particles in a solution by passing electricity through the liquid
eosinophil
type of granulocyte
erythrocyte
mature RBC
erythropoietin
hormone released by the kidneys to stimulate RBC production
fibrin clot
clot-forming threads formed at the site of an injury during coagulation where platelets clump together with various other substances
fibrinogen
protein in plasma that aids in clotting
gamma globulin
globulin that arises in lymphatic tissue and functions as part of the immune system
globin
protein molecule in the blood, a part of hemoglobin
globulin
any of a family of proteins in blood plasma
granulocyte
leukocyte with granular cytoplasm
hematocrit
measure of the percentage of RBCs in a blood sample
hematocytoblast
most immature blood cell
heme
pigment containing iron in hemoglobin
hemoglobin
protein in RBCs essential to the transport of oxygen
heparin
substance in blood that prevents clotting
histamine
substance released by basophils and eosinophils; involved in allergic reactions
leukocyte
mature WBC
lymphocyte
type of agranulocyte
megakaryocyte
large cells in red bone marrow that form platelets
monocyte
type of agranulocyte
neutrophil
type of leukocyte; granulocyte
plasma
liquid portion of unclotted blood
plasmapheresis
process of removing blood from a person, centrifuging it, and returning only RBCs to that person
platelet
thrombocyte; part of a megakaryocyte that initiates clotting
prothrombin
type of plasma protein that aids in clotting
RBC
one of the solid parts of blood formed from stem cells and having hemoglobin within; erythrocyte
RBC count
measurement of RBCs in a cubic millimeter of blood
Rh factor rh(esus monkey)
type of antigen in blood that can cause a transfusion reaction
Rh-negative
lacking Rh factor on surface of blood cells
Rh-positive
having Rh factor on surface of blood cells
serum
the liquid left after blood has clotted
stem cell
immature cell formed in bone marrow that becomes differentiated into either a red or a white blood cell
thrombin
enzyme that helps in clot formation
thrombocyte
platelet; cell fragment that produces thrombin
thromboplastin
protein that aids in forming a fibrin clot
transfusion
injection of donor blood into a person needing blood
WBC
one of the solid parts of blood from stem cells that plays a role in defense against disease; leukocyte
