Each reaction of the cascade results from an assembly of a complex in which an enzyme (an activated coagulation factor), a substrate (a coagulation factor in the form of a proenzyme) and a cofactor (a reaction accelerator) intervene. Assembly of these components occurs on a phospholipid complex, and they remain bound to
each other owing to the action of calcium ions.
Thus, coagulation occurs in sites where this binding is possible (endothelium, activated platelet surface). Coagulation pathway is divided into an extrinsic pathway (activated by tissue factor, which is a cell lipoprotein that is fully functional in the presence of tissue damage), and an intrinsic pathway, both of which converge at the activation of factor X. Notwithstanding that, both pathways are interrelated. Once the cascade process starts, it becomes restricted to the site of the lesion in order to prevent it from spreading to the vascular network.
El ensamblaje de estos componentes se produce sobre un complejo de fosfolípidos y se mantienen juntos debido a iones de calcio. Por esta causa, la coagulación se produce en los lugares donde es posible este ensamblaje (endotelio, superficie de las plaquetas activadas). La vía de la coagulación se divide en vía extrínseca (activada por el factor tisular, lipoproteína celular que queda al descubierto cuando hay una lesión tisular) y vía intrínseca, ambas confluyen en la activación del factor X. No obstante, ambas vías están interrelacionadas. Una vez que se inicia el proceso de la cascada, el mismo queda restringido al sitio de la lesión para evitar que se propague a toda la red vascular.
