Clotting definition
Definition
Refers to a physiologic process in which the blood is converted from a liquid state to semisolid gel.
Term
Thrombus
Definition
A blood clot formed in situ within the vascular system of the body and impeding blood flow.

Term
Hematopoiesis
Definition
The production of all types of blood cells including formation, development, and differentiation of blood cells.
Term
Hemostasis
Definition
The stopping of a flow of blood.
Term
Systemic Clotting Problem
Definition
Problem extends to entire body; is usually the result of a significant hematologic event.
Term
Localized Clotting Problem
Definition
Problem is localized; is usually a problem in a vein or an artery, either injury to a vessel or a clot within a vessel.
Term
Platelet Aggregation
Definition
Damage to blood vessel has immediate reflex that promotes vasoconstriction, thus diminishing blood loss. Begins by forming a platelet plut by having platelets clump togehter, a process essential for blood clotting.
Term
Fibrinolysis
Definition
Prevents over-enlargement of the fibrin clot. Limits size of blood clots by activating plasminogen to plasmin.
Term
Plasmin
Definition
Digests fibrin, fibrinogen, and prothrombin.
Term
Systemic Bleeding S/S
Definition
Ecchymosis, petechiae, purpura, frequent nosebleeds, blood in stool, urine, emesis, bleeding gums, bleeding within joints, and excessive menstrual bleeding.
Term
Localized Bleeding S/S
Definition
Bleeding or ecchymosis at injury site, bleeding at surgical site, and intracranial bleeding.
Term

Definition
Substances that prevent or delay coagulation of the blood.
Term

Term
Aminocaproic acid
Definition
Prevents clot destruction
Term

(DIC)
