Question 2

involved with stopping blood flow from injured vessels
•complex cascade of clotting factors
•formation of insoluble fibrin that “plugs” vessel

Answer 2

hemostatic system

1st of normal clotting DIC

Question 3

process in which fibrin is broken down in fibrin degradation products(FDP) and normal circulation restored
-Breaks down fibrin so it doesn’t stick together

Answer 3

fibrinolytic system

2nd of normal clotting DIC
