A thrombus (), or blood clot , is the final product of the blood coagulation step in hemostasis . It is achieved via the aggregation of platelets that form a platelet plug, and the activation of the humoral coagulation system (i.e. clotting factors). A thrombus is normal in cases of injury , but pathologic in instances of thrombosis . Mural thrombi are thrombi adherent to the vessel wall. They are not occlusive and affect large vessels, such as heart and aorta . Grossly they appear grey-red with alternating light and dark lines ( lines of Zahn ) which represent bands of fibrin (lighter) with entrapped white blood cells and red blood cells (darker).
