Hemostasis
Vascular spasm : The constriction of the blood vessel helps to slow down the flow of blood and allows other hemostatic mechanisms, such as platelet plug formation and blood clotting, to effectively seal the wound.
Platelet plug formation: Activated platelets release various chemical signals such as ADP (adenosine diphosphate) and thromboxane A2, which attract more platelets to the site, promoting further platelet aggregation. As the platelet plug grows, it helps to seal the breach in the blood vessel, reducing the flow of blood and preventing excessive blood loss.
Blood clotting: The process is initiated by the exposure of blood to tissue factors, triggering a cascade of reactions that activate various clotting factors. This leads to the formation of thrombin, which converts soluble fibrinogen into insoluble fibrin threads. The mesh-like network of fibrin traps blood cells and platelets, creating a durable clot that seals the wound and promotes tissue repair. The intricate balance of coagulation factors and inhibitors ensures that clotting is localized and controlled, preventing the formation of unwanted clots within the blood vessels, which could lead to serious health complications such as thrombosis or embolism.
