Definitions:

Fibrinolysis

The biological process by which fibrin clots, the products of coagulation, are broken down, thereby preventing blood clots from growing and becoming problematic.

Intrinsic Pathway

A series of steps in blood coagulation that is initiated by internal trauma, leading to the activation of Factor X independent of tissue factor.

Extrinsic Pathway

A pathway for blood coagulation that is initiated by external trauma leading to blood escaping from the vascular system.

Clot Retraction

Condensation of a clot into a denser, compact structure; caused by the elastic nature of fibrin.
