Module 13: Blood System Flashcards
the difference between plasma and serum is that
serum does not contain clotting elements
person with _____ blood are referred to as universal recipients
type AB
colony stimulating factors
trigger the production, maturation, and activation of granulocytes
coagulation
the process of blood clotting
_______ is the blood protein that enables the transport of oxygen
hemoglobin
granulocytes are formed in red bone marrow, or ____ tissue
myeloid
thrombin
enzyme that converts fibrinogen to fibrin during coagulation
antibodies
protein substances stimulated by the presence of antigens
bilirubin
formed by the release of iron in the breakdown of hemoglobin
albumin
the protein that maintains proper proportion and concentration of water in blood
fibrinogen
protein converted to fibrin in the clotting process
globulin
the portion of plasma that contains antibodies to protect the body against antigens
erythropoietin
the hormone secreted by the kidneys to stimulate the bone marrow to make RBCs
prothrombin
plasma protein converted to thrombin in the clotting process
basophil
a blood cell that contains heparin and histamine
immunoglobulins
antibodies that bind to and sometimes destroy antigens, or foreign substances
hematopoiesis
the formation of blood cells is
hemolytic anemia
the reduction in red blood cells due to excessive destruction
epstein-barr is the virus that causes
mononucleosis
-cytosis
abnormal condition of cells
purpura
multiple pinpoint hemorrhages and accumulation of blood under the skin
in acute myeloid leukaemia there is an increased number in
malignant immature leukocytes
thalassemia
an inherited defect in the ability to produce hemoglobin usually seen in person of mediterranean background
polycythemia vera
characterized by an abnormal increase in the number of red blood cells
hemophilia
excessive bleeding caused by a congenital lack of one of the protein factors necessary for clotting
leukemia
general term meaning disease of bone marrow with malignant WBCs filling the marrow and bloodstream
aplastic anemia
when bone marrow fails to produce red blood cells
hemochromatosis is characterized by
excess iron deposits throughout the body
in some anemias, irregularly shaped blood cells are formed, a condition known as __________
poikilocytosis
coagulation time
the time required for venous blood to clot in a test tube
which test would be given before a blood transfusion?
Coombs test
this test is used to evaluate patients taking anticoagulant medications
prothrombin time
the separation of blood into its component parts by spinning a blood sample at high speeds in a centrifuge
apheresis
hematocrit
percentage of erythrocytes in a volume of blood
antiglobulin test
a laboratory test for the presence of antibodies that coat and damage erythrocytes
the administration of packed cells is treatment for
anemia
this test determines the number of clotting cells per cubic millimetre of blood
platelet count
this test determines the number of clotting cells per cubic millimetre of blood
platelet count
a person with type o blood is a
universal donor
globulin
a plasma protein that serves as a defence mechanism of the immune system
the primary function of platelets is to
promote blood clotting
granulocytopenia
a deficiency in the total number of basophils, eosinophils, and neutrophils
hemophilia
hereditary bleeding disorder caused by a deficiency in the factors needed for blood to clot
what is an anticoagulant substance found in blood and tissue cells
heparin
in pernicious anemia, RBC production is decreased due to lack of protein called
intrinsic factor
someone with pernicious anemia will need lifelong administration of what substance?
vitamin B12
mononucleosis
presents with symptoms of fatigue, weakness and pharyngitis along with EBV antibodies
the blood protein in RBCs that enables the RBCs to carry oxygen is called
hemoglobin
stem cells
unspecialized cells that become specialized when they mature
eosinophils
increase in allergic reactions
_________ are phagocytic granulocytes
neutrophils
heme is broken apart into iron and the pigment ______
bilirubin
the medical term for large bluish-purple spots of leaked blood under the skin, commonly called bruising is
ecchymoses
