Detailed explanation-1: -so that they stick to the injured area. The “glue” that holds platelets to the blood vessel wall is von Willebrand factor, a large protein produced by the cells of the vessel wall. The proteins collagen and thrombin act at the site of the injury to induce platelets to stick together.
Detailed explanation-2: -Following vasoconstriction, exposed collagen from the damaged surface will encourage platelets to adhere, activate and aggregate to form a platelet plug, sealing off the injured area.
Detailed explanation-3: -Primary hemostasis (platelet clotting) Primary hemostasis is when your body forms a temporary plug to seal an injury. To accomplish that, platelets that circulate in your blood stick to the damaged tissue and activate.
