Disseminated Intravascular Coagulation (DIC) represents an end-stage systemic state of global hemostatic dysfunction occurring secondary to a wide variety of insults. DIC is characterized by wide-spread inappropriate activation of both platelets aggregation and coagulation within the microcirculation, yielding the generation of micro- thrombi throughout the micro-vasculature.

Both the contact pathway and the tissue factor feed into and activate the common pathway. Tissue factor pathway (extrinsic pathway) This pathway generates the thrombin bust that leads to the release of thrombin from the complex prothrombinase. Thrombin is a very important component of the coagulation cascade as it activates feedback. It also activates the other components of the coagulation cascade.

Coagulation pathway

Coagulation is a complicated subject and is greatly simplified here for the student's understanding. To stop bleeding, the body relies on the interaction of three processes: Primary hemostasis involves the first two processes. The entire process of coagulation is directed toward creating fibrin, a highly fibrous protein that essentially forms a mesh, entrapping blood cells and platelets, creating an unyielding gel-like substance that can prevent blood loss from large tears in the vasculature. The extrinsic pathway of blood coagulation Upon the introduction of cells, particularly crushed or injured tissue, blood coagulation is activated and a fibrin clot is rapidly formed. The protein on the surface of cells that is responsible for the initiation of blood clotting is known as tissue factor, or tissue thromboplastin.

Injury to blood vessels. Injury to a blood vessel results to exposure of materials that are not normally … Final Common Pathway However the coagulation cascade is organized, the final key step is generation of fibrin which is created by cleavage of the precursor fibrinogen, a soluble protein that is present at high concentration within plasma. 1.

Alternatively, coagulation may be initiated through the “intrinsic pathway” when factor XII is activated on a charged surface by a process called contact activation. 20–22 Activation of factor XII is followed sequentially by activation of factor XI and factor IX.

Describe and understand methods of platelet 2017-07-05 · Coagulation cascade has two pathways known as intrinsic and extrinsic pathway. The key difference between intrinsic and extrinsic pathways in blood clotting is their initiation factors. The intrinsic pathway starts when there is a trauma in blood or when blood is exposed to a collagen .

Coagulation cascade is activated by 2 pathways, the extrinsic and intrinsic which culminates into a common pathway. The factors involved in common pathway can be remembered by a mnemonic: 1 X 2 X 5 = 10 . Blood coagulation results from a series of proteolytic reactions involving the step-wise activation of coagulation factors. Subsets of these factors can be activated by two distinct pathways, the extrinsic or tissue damage pathway, and the intrinsic or contact pathway. In the coagulation cascade, chemicals called clotting factors (or coagulation factors) prompt reactions that activate still more coagulation factors. The process is complex, but is initiated along two basic pathways: The extrinsic pathway, which normally is triggered by trauma.
