HOSA: 3 Clinical Lab- Hematology and Hemostasis

adhesion

act of two parts sticking together

aggregation

separate objects becoming one large mass

coagulation

the process of forming a fibrin clot

emboli

large masses of material that block blood vessels (clot)

endothelium

the layer of the epithelial (skin) cells that lines blood vessels

fibrin

protein formed by fibrinogen through the action of thrombin

Fibrinogen

plasma protein produced from the liver and converted into fibrin through thrombin

fibrinolysis

enzymatic breakdown of a blood clot

hemorrhage

excessive/uncontrollably bleeding

heparin

Anticoagulant drug that stops thrombin

inhibitor

stops a process

intravascular

INSIDE the blood vessel

megakaryocyte

bone marrow cell that produces platelets

plasmin

an enzyme that dissolves the fibrin of blood clots

plasminogen

comes before plasmin

prothrombin

comes before thrombin

thrombin

enzyme that converts fibrinogen to fibrin during coagulation

thromboplastin

substance present in tissues, platelets, and leukocytes that is necessary for coagulation

aka tissue factor

thrombus

stationary blood clot

vascoconstriction

the constriction of blood vessels, which increases blood pressure.

warfarin

anticoagulant drug taken to prevent blood clotting by inhibiting vitamin K (promotes blood clotting) dependent factors
