Platelets are key players in hemostasis, the process by which the body seals a ruptured blood vessel and prevents further loss of blood. Although rupture of larger vessels usually requires medical intervention, hemostasis is quite effective in dealing with small, simple wounds.

Hemostasis has four key steps in stopping bleeding; Vasoconstriction: Blood vessels constrict to slow blood flow. Primary hemostasis: Platelets clump together, forming a sticky plug to fill the wound. Secondary hemostasis: Fibrin strands weave a mesh, reinforcing the clot. Fibrinolysis: Plasmin enzymes dissolve the clot when healing is complete.
As soon as a blood vessel wall is damaged, a series of reactions activates platelets 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.

Hemostasis is the physiological process by which bleeding ceases. Hemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, in which clotting factors promote the formation of a fibrin clot. Fibrinolysis is the process in which a clot is degraded in a healing vessel.
