Platelet Function The main function of platelets is a responsibility in the formation of blood clots during hemostasis. This is the most common and often described role of the blood component, whereas the remaining functions remain less known.

Coagulation and platelet activation have turned out to be tightly integrated processes. Thrombin, the key enzyme in the coagulation cascade, is a potent platelet agonist, acting on the platelet PAR receptors 1 and 4, and conversely, activated platelets are known to enhance and contribute to the overall coagulation process via several independent mechanisms (reviewed in [60, 61]).

Vasoconstriction is a reflex in which blood vessels narrow to increase blood pressure. Next, platelet plug formation involves the activation, aggregation, and adherence of platelets into a plug that serves as a barrier against blood flow. Coagulation involves a complex cascade in which a fibrin mesh is cleaved from fibrinogen.

They limit blood loss after injury by clumping together in a mesh-like structure formed by fibrin strands hence preventing further oozing of blood from infected vessels. Coagulation and Platelet Disorders Hemostasis depends on vascular integrity, platelet numbers and function, and coagulation. Vascular integrity is determined in large measure by the health of endothelial cells and their extracellular matrix. Damage to vessel walls can result in hemorrhage and/or activation of platelets and coagulation. Coagulation disorders can result in either too little blood clotting (hemorrhage) or too much blood clotting (thrombosis). Platelets are a type of blood cell that help create temporary plugs to form blood clots and stop bleeding.
