Final answer:
Factor XIII is known as the fibrin stabilizing factor, which is crucial for stabilizing the fibrin meshwork in the final stages of the coagulation process to form a blood clot.
Step-by-step explanation:
Factor XIII is known as the fibrin stabilizing factor. The clotting factors are crucial in the coagulation process, where they work systematically to stop bleeding and form a blood clot. Factor XIII plays a pivotal role in the final stages of clot formation, acting in the common pathway, stabilizing the fibrin meshwork that has been created by earlier steps of coagulation, such as the intrinsic and extrinsic pathways which involve other clotting factors. The liver plays a significant role in the production of coagulation factors, and several anticoagulants naturally exist in the bloodstream, such as antithrombin and heparin, to regulate clotting and prevent excessive blood clot formation.
