You don't bleed to death from a cut primarily because of your body's hemostatic mechanisms, which include blood vessel constriction, platelet aggregation, and the coagulation cascade. When a blood vessel is damaged, it constricts to reduce blood flow, while platelets quickly gather at the injury site to form a temporary plug. The coagulation cascade then activates various proteins that reinforce this plug, leading to the formation of a stable blood clot. These processes work together to limit blood loss and promote healing.
