Final answer:
Hemostasis is the correct sequence of responses to stop bleeding after an injury, it includes vascular spasm, platelet plug formation, and coagulation. After initial clotting, the body continues to release clotting factors to strengthen the seal on the damaged vessel.
Step-by-step explanation:
Hemostasis is a sequence of responses that stop bleeding. It is the physiological process by which the body ceases blood loss. Hemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, where clotting factors lead to the formation of a fibrin clot which seals the site of injury. Fibrinolysis is the process where the clot is broken down during vessel healing. Conditions like hemorrhage can overwhelm these mechanisms, requiring medical intervention to restore blood volume.
In response to a skin injury, after the initial clot formation, the next response is typically the release of additional clotting substances which further the process of clotting and sealing the damaged vessel.

Vascular spasm constricts the flow of bloodPlatelet plug formation temporarily seals vessel openingsCoagulation leads to repair of the vessel wall after bleeding has stopped
