Study Notes
Hemostasis Process
- Fibrinogen plays a primary role in hemostasis by converting into fibrin, which forms a clot to stop bleeding.
Phases of Hemostasis
- The coagulation phase involves the formation of an insoluble fibrin clot, which is essential for hemostasis.
Thrombosis
- The main cause of thrombosis is the formation of a blood clot (thrombus) inside a blood vessel, which can obstruct blood flow.
Vasoconstriction
- Vasoconstriction plays a crucial role in hemostasis by reducing blood flow to the injured area, thereby minimizing blood loss.
Fibrin Digestion
- Plasmin is responsible for the continual process of fibrin digestion, which helps to dissolve blood clots.
Heparin Sulfate
- Heparin sulfate, present in the blood vessel, inhibits thrombin and prevents excessive blood clotting.
Tissue Factor
- The endothelium, the innermost layer of the blood vessel, contains tissue factor that activates coagulation and fibrin formation.
Platelet Function
- The primary function of platelets during the stoppage of bleeding is to form a platelet plug, which is reinforced by fibrin to create a stable clot.
