Blood clotting or coagulation is a complex process that helps us survive when An image of both the intrinsic and extrinsic pathways of the clotting cascade 

Extrinsic Pathway - Due to the release of tissue factor (factor II) because of an external will be interrupted therefore leading to a reduction in blood coagulation. 27 Oct 2009 In the extrinsic pathway, plasma factor VII is activated in the presence of its cofactor, tissue factor (TF), forming the factor VIIa/TF complex (FVIIa/  It activates the extrinsic coagulation pathway, and induces the formation of a fibrin clot.

Coagulation cascade. This is the currently selected item. Life and this pathway which I'll circle here and I apologize for the poor organization this one is known as the extrinsic pathway extrinsic so what's the difference between these two pathways well it turns out that the extrinsic pathway is the spark it's the one that gets activated

Intrinsic Pathway: Which begins in blood itself 5. Both of these then merge into a common pathway to complete the clotting process. The prothrombin time (PT) test evaluates how well all of the coagulation factors in the extrinsic and common pathways of the coagulation cascade work together. Included are: factors I (Fibrinogen), II (Prothrombin), V, VII and X. extrinsic pathway: initial coagulation pathway that begins with tissue damage and results in the activation of the common pathway. fibrin: insoluble, filamentous protein that forms the structure of a blood clot. fibrinolysis: gradual degradation of a blood clot.

Extrinsic pathway coagulation

Fibrin has been formed, and the test is done. So yes: people with a normal coagulation system have a normal PT despite the fact that the extrinsic pathway only plays an initial role in coagulation. The clotting factors involved in both intrinsic and extrinsic pathways are shown in figure 1. Figure 1: Clotting Factors The intrinsic pathway is activated by the binding of factor XII to a negatively-charged foreign surface that is exposed to blood. Conversely, the extrinsic pathway is called extrinsic because it’s activated by tissue factor found extrinsically, or outside of the blood. Both pathways can become activated independently and ultimately culminate in the activation of factor X, which then proceeds to activate the rest of the coagulation cascade via the common pathway.
