Overview of Hemostasis
Hemostasis is the natural process that stops blood loss when an injury occurs.

Vascular Spasm
Vasoconstriction is the narrowing of the blood vessels, which reduces blood loss during injury.

Platelet Plug Formation
At the site of vessel injury, platelets stick together to create a plug, which is the beginning of blood clot formation.

Coagulation
Coagulation is the process by which a blood clot forms to reduce blood loss after damage to a blood vessel.

Role of Vitamin K
Vitamin K is an essential factor of the coagulation cascade.

Clot Retraction and Repair
Clot retraction is the shrinking of a blood clot facilitated by thrombolytic agents.

Fibrinolysis
Fibrinolysis is a process of breaking down clots in order to prevent them from growing and becoming problematic.
