Hemostasis: Stages and How the Process Stops Blood …

WebHemostasis is the process by which blood loss from a damaged vessel is stopped. This involves the formation of a clot. Blood clotting is achieved by a cascade of enzymatic reactions, which involves several factors. Among them are the zymogens prekallikrein, prothrombin, factors VII, IX, X, XI, and XII, which are converted to active proteases by ... WebHemostasis is an active process regulating the formation and disso-lution of ﬁbrin clot to preserve vascular integrity. The different phases of hemostasis are coordinated so that effective clotting occurs only at the site of vascular injury while maintaining blood ﬂow in other parts of the circulation.
