The<unk> , also known as the hemostatic<unk>  or<unk>  thrombus, is an aggregation of<unk> s formed during early stages of hemostasis in response to one or more injuries to blood vessel walls. After<unk> s are recruited and begin to accumulate around the breakage, their “sticky” nature allows them to adhere to each other. This forms a<unk> , which prevents more blood from leaving the body as well as any outside contaminants from getting in. The<unk>  provides a temporary blockage of the break in the vasculature. As such,<unk>  formation occurs after vasoconstriction of the blood vessels but before the creation of the fibrin mesh clot, which is the more permanent solution to the injury. The result of the<unk>  formation is the coagulation of blood. It can also be referred to as primary hemostasis.
