Hemostasis

The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION. |

Hemostasis Categories.
 |
Blood Coagulation - The process of the interaction of BLOOD COAGULATION FACTORS that results in an insoluble FIBRIN clot. |
|
Platelet Activation - A series of progressive, overlapping events, triggered by exposure of the PLATELETS to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable hemostatic plug. |
