Bleeding Disorders



Hemostasis

 

 

 

• Hemostasis is the arrest of blood flow and control of hemorrhage from an injured blood vessel.

 

• The entire mechanism of hemostasis can be divided into three parts: 1. Extravascular effects

2. Vascular effects:

 

i.     Vasoconstriction: serotonin by plasma

 

ii. Platelet Plug: collagen contact with platelet and platelet release ADP then serotonin and factor 3 participates in coagulation.

 

3. Intravascular effects: Intrinsic factor to form a fibrin clot.
