Extrinsic Pathway
Vascular Injury
At the site of injury
collagen and tissue factor
are exposed to coagulation
factors in the blood
activating the extrinsic and
intrinsic pathways.
Prothrombin and coagulation
factors VII, ,IX and X are
transported via golgi
apparatus vesicles into the
blood.

Golgi Apparatus
The fibrin mesh/clot forms
at the site of vascular
injury, blocking the leaking
blood.
