Hemostasis: Integrity of the blood vessel is necessary to carry blood tissues. Damage to the vascular wall is repaired by hemostasis, which involves the formation of a thrombus at the site of vessel injury. Hemostasis has two phases: Primary and Secondary. Primary hemostasis is mediated by the interaction between platelets and the vessel wall to form a weak platelet plug. Secondary hemostasis is mediated by the coagulation cascade and stabilizes the platelet plug.
Hemostasis is the process of preventing blood loss which depends on vascular endothelium, platelets, and the coagulation cascade.
