Formation of the platelet plug Second stage of hemostasis, 1. platelets are attracted to damaged vessel wall. 2. activation by sub-endothelial tissue. 3. change from smooth disks to spiny spheres. 4. exposing glycoprotein receptors on their surfaces. This step requires a protein molecule called von Willebrand factor that leaks into the injured tissue from the plasma. (adhesion, activation, aggregation) During :emostasis, platelets change from .....Smooth disks to spiny spheres von Willebrand factor Formation of the platelet plug requires a protein molecule called (helps platelets stick together) Glycoprotein Receptors Exposed during the formation of the platelet plug when platelets change from smooth disks to spiny spheres 1.Blood coagulation or development of an insoluble fibrin clot Third
