The Fibrinolysis is the method that avoids the blood clot from developing and being complicated.There are primary and secondary Fibrinolysis. The primary fibrinolysis is a usual body activity and the secondary fibrinolysis is a seizing up of the clots because of antibiotics,a disease etc..

In this process,the compound of coagulation called as fibrin clot is deteriorated.The enzyme called as plasmin breaks the fibrin at different regions,resulting in the making of flowing remnants which are cleaned by alternative proteases or with the help of liver.
