Explanation:
Detailed explanation-1: -1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.
Detailed explanation-2: -Platelet plug formation: Fibrinogen forms bridges between activated platelets to form the platelet plug.
Detailed explanation-3: -It builds glycoprotein IIb/IIIa in the platelet membrane and constitutes a fibrinogen receptor, which also exhibits an ability to bind the von Willebrand factor, fibronectin, and thrombospondin. Activated GPIIb-IIIa binds fibrinogen or von Willebrand factor, which forms molecular bridges between aggregating platelets.
