<P> Fibrinolysis is a process that prevents blood clots from growing and becoming problematic . This process has two types: primary fibrinolysis and secondary fibrinolysis . The primary type is a normal body process, whereas secondary fibrinolysis is the breakdown of clots due to a medicine, a medical disorder, or some other cause . </P> <P> In fibrinolysis, a fibrin clot, the product of coagulation, is broken down . Its main enzyme plasmin cuts the fibrin mesh at various places, leading to the production of circulating fragments that are cleared by other proteases or by the kidney and liver . </P> <P> Plasmin is produced in an inactive form, plasminogen, in the liver . Although plasminogen cannot cleave fibrin, it still has an affinity for it, and is incorporated into the clot when it is formed . </P>
