Blood coagulation and fibrinolysis: an overview
1Department of Medicine, University of Wisconsin, Madison 53706.
Recent advances in the understanding of blood coagulation provide strong evidence that exposure of tissue factor is the "match" which initiates blood coagulation. A novel plasma protease inhibitor, called EPI or LACI, effectively extinguishes this "match," leaving Factors IXa, VIII, X, V, and II to function as a "fuse." Activated Factors IX, X, and II are controlled by heparin-enhancable protease inhibitors. Activated Factors VIII and V are destroyed by the protein C/S system. Fibrinolysis is largely cell-based and controlled by differential secretion of plasminogen activators and plasminogen activator inhibitors.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
