What is the stopping of bleeding called?

The stopping of bleeding is called hemostasis. This process involves various physiological mechanisms that work to constrict blood vessels, activate platelets, and initiate the clotting cascade to prevent further blood loss. Hemostasis can occur through primary mechanisms, such as platelet aggregation, and secondary mechanisms that involve the formation of a fibrin clot. In medical contexts, interventions may also be employed to enhance hemostasis in cases of severe bleeding.
