movement of a cell toward the greater concentration of a substance

leukocytosis

too many WBCs in the blood

leukopenia

too few WBCs in the blood

platelet

cellular fragment formed in the bone marrow that helps blood clot

thrombocyte

another term for blood platelet

thrombopoietin

a hormone that stimulates megakaryocytes to proliferate and yield platelets

serotonin

vasoconstrictor that blood platelets release when blood vessels break, controlling bleeding

plasma protein

protein dissolved in blood plasma

albumin

plasma protein that makes a major contribution to the colloid osmotic pressure of plasma

fibrinogen

plasma protein converted into fibrin during blood coagulation

nonprotein nitrogenous substances (NPNs)

a nitrogen-containing molecule that is not related to a protein

hemostasis

stoppage of bleeding

coagulation

blood clotting

fibrin

insolube, fibrous protein formed from fibrinogen during blood coagulation

prothrombin

plasma protein that functions in blood clotting

thrombin

blood-clotting enzyme that catalyzed formation of fibrin from fibrinogen

fluid portion of coagulated blood

thrombus

blood clot that remains where it forms in a blood vessel

embolus

blood clot, bubble, or other object carried in circulation that may obstruct a blood vessel

agglutination

clumping of blood cells in response to a reaction between an antibody and an antigen

antibody

protein that B cells of the immune system produce in response to a non-self antigen; reacts with an antigen

antigen

chemical that stimulates B lymphocytes to produce antibodies

oxyhemoglobin

compound formed when oxygen binds hemoglobin

deoxyhemoglobin

hemoglobin that has released oxygen

carbaminohemoglobin

bonded carbon dioxide and hemoglobin

hematopoiesis

production of blood and blood cells

formed elements

blood cells

neutrophil

WBC that is much larger than RBCs, is phagocytic and is the 1st WBCs to arrive at infections

eosinophil

WBC that functions to moderate allergic reactions and defend against parasitic worm infestations; phagocytic, granulocyte

basophil

WBCs that release histamine to attract other WBCs and releases the anticoagulant heparin. granular, phagocytic

monocytes

largest WBC and those that leave the bloodstream to become macrophages, agranular

lymphocytes

smallest WBCs that function in immunity. There are T and B type

myelocytic leukemia

cancer that involves increase in myeloblasts

lymphocytic leukemia

cancer that involved an increase in lymphocytes in the bloodstream

embolism

condition when abnormal blood clots break loose and block flow of the blood through blood vessels and capillaries

polycythemia

excess of RBCs being produced, resulting in slower flow of blood because of increased blood viscosity

thrombocytopenia

condition where the # of circulating platelets is deficient

hemophelia

hereditary bleeding disorder caused by lack of clotting factors
