Final answer:
The complex process that leads to the formation of fibrin from fibrinogen is called coagulation. Coagulation is a cascade process in which fibrinogen is converted into fibrin to create a clot.c) Coagulation
Step-by-step explanation:
The complex process that leads to the formation of fibrin from fibrinogen is called coagulation. Coagulation is a cascade process in which fibrinogen, a plasma protein, is converted into fibrin, forming a mesh that traps platelets and blood cells to create a clot. This process is an essential part of hemostasis, which is the physiological process that stops bleeding.
