WebPlatelets are a central component of many restorative physiological processes, including hemostasis. During hemostasis, damaged subendothelium releases adhesive proteins (ie, collagen and thromboplastin) and fibrinogen, which bind with aggregated plate-lets at the site of injury, forming a platelet plug.
