The body stops injured blood vessels from bleeding by the process of hemostasis, which includes blood clotting, according to Merck Manual. The three-step process first involves the blood vessels constricting, which slows the blood flow and allows clotting to begin. Platelets, which are blood particles similar to cells, then help form clots by creating a mesh that seals the injury. Finally, thrombin and collagen, two proteins in the blood, act on the platelets, which change shape, stick together and attract more platelets to the area of injury to produce the clot.
