Blood coagulation or clotting process

Question

Explain how blood coagulation (or clotting) process be explained?

Answer 1

Blood clotting encompasses a series of chemical reactions whose relevant products are enzymes which catalyze the following reactions (that is, why the clotting reactions are termed as cascade reactions). In plasma thromboplastinogen converts into thromboplastin, a reaction triggered by the tissue and platelet factors released after injury of the blood vessel. Thromboplastin then catalyzes all along with calcium ions, the conversion of prothrombin into thrombin. Thrombin then catalyzes a reaction which generates fibrin from fibrinogen. Fibrin, as an insoluble substance, precipitates to make a network which traps red blood cells and platelets making the blood clot and having the hemorrhage.
