Coagulation cascade is a normal physiological process which aims at preventing significant blood loss or hemorrhage following vascular injury. Unfortunately, there are times when a blood clot (thrombus) will form when it is not needed. For instance, some high risk conditions such as prolonged immobilization, surgery, or cancer can increase the risk of developing a blood clot which can potentially lead to significant consequences. http://www.differencebetween.net/science/health/drugs-health/difference-between-heparin-and-warfarin/
