Blood-clotting proteins circulate in the blood plasma in an inactive form, poised to participate in blood coagulation upon tissue injury. Blood-clotting proteins generate thrombin, an enzyme that converts fibrinogen to fibrin, and a reaction that leads to the formation of a fibrin clot.
At each stage, more clotting factors are activated. The final stage is conversion of the protein fibrinogen, which is dissolved in the fluid part of the blood, to insoluble fibrin strands. The sticky fibrin threads form a tangled mesh that traps red cells and other blood cells, forming a clot.
