Blood clotting pathway diagram

WebBlood clotting is considered part of the Positive Feedback (PF) Loop. This is defined as an effector that will AMPLIFY the effect of the Negative Feedback (NF) Loop. For instance, when there is a hemorrhage (loss of blood), it will cause a sequential activation of clotting factors. Here, a single clotting factor results in the activation of ... WebBlood clotting involves three steps. First, vascular spasm constricts the flow of blood. Next, a platelet plug forms to temporarily seal small openings in the vessel. Coagulation then enables the repair of the vessel wall once the leakage of blood has stopped.

WebThere are two main mechanisms for triggering the blood clotting, termed the tissue factor pathway and the contact pathway. Only one of these pathways (the tissue factor pathway) functions in normal hemostasis. Both pathways, however, are thought to contribute to thrombosis.

Physiologist Johannes Müller (1801–1858) described fibrin, the substance of a thrombus. Its soluble precursor, fibrinogen, was thus named by Rudolf Virchow (1821–1902), and isolated chemically by Prosper Sylvain Denis (1799–1863).
