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: -Hence, the correct order of the given terms in a logical sequence is Platelets, Thromboplastin, Thrombin, Fibrinogen, Fibrin.
Detailed explanation-3: -coagulation. …of prothrombin (factor II) to thrombin (factor IIa). Thrombin, in turn, catalyzes the conversion of fibrinogen (factor I)-a soluble plasma protein-into long, sticky threads of insoluble fibrin (factor Ia). The fibrin threads form a mesh that traps platelets, blood cells, and plasma.
Detailed explanation-4: -The correct answer is option A. During blood vessel injury, thromboplastin is formed which catalyzes the conversion of prothrombin into thrombin. Thrombin then converts fibrinogen into fibrin, which secures the platelets to form a rigid hemostatic plug.
