Within the haemostatic system, complex processes are at play. These act to maintain the blood in a liquid state within the intact vascular system, while at the same time allowing clot formation in areas where damage, through both injury and natural ‘wear and tear’, has occurred to the vascular endothelium. Multiple mechanisms are involved to both promote and inhibit blood coagulation in order to maintain the balance. A further role of haemostasis is the limitation of any coagulation to the site of injury. This means that the haemostatic system requires additional functionality in order to break down clots and therefore restore normal blood flow to the state which existed prior to vascular injury.
