And in this way, you prevent the loss of blood. So of course, there are many other hemostasis proteins that are involved in this process, but the platelet brick wall, if you like, would indeed be weak without 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.
