[Answer] What prevents fibrin from forming a mesh in a healthy unbroken blood vessel? The formation of a fibrin mesh depends on the blood being exposed to air. Fibrinogen is restricted to sites where platelets have aggregated. When thrombin is not bound to fibrin it is inactivated by antithrombin. The speed at which blood circulates prevents the accumulation of platelets and fibrin strands.

Answer: When thrombin is not bound to fibrin it is inactivated by antithrombin.Thrombin could initiate fibrin mesh formation if it were not deactivated in the normal blood circulation. Antithrombin III a plasma protein and other anticoagulants help prevent thrombin from activating fibrinogen into fibrin.

Thu Jun 22 2017 · When there is an injury a protease enzyme called thrombin acts on fibrinogen and causes it to polymerize into fibrin which is an insoluble gel-like protein. Then fibrin together with platelets creates a blood clot on the wound site to prevent continued bleeding. The formation of fibrin is totally dependent on thrombin generated from prothrombin.
