Clotting factors are components found in plasma that are linked to the blood clotting process. These factors are named and numbered based on their discovery.
Though there are a total of 13 numerals, there are only 2 clotting factors. Factor VI was discovered to be part of another factor.
The clotting factors are Factor I (fibrinogen), Factor II (prothrombin), Factor III (tissue thromboplastin or tissue factor), Factor IV (ionized calcium), Factor V (labile factor or proaccelerin), Factor VII (stable factor or proconvertin), and Factor VIII (antihemophilic factor).
Additionally, the coagulation factors also include Factor IX (plasma thromboplastin component or the Christmas factor), Factor X (Stuart-Prower factor), Factor XI (plasma thromboplastin antecedent), Factor XII (Hageman factor), and Factor XIII (fibrin-stabilizing factor).
The liver uses vitamin K to produce some of the factors such as Factors II, VII, IX, and X.
Normally, vitamin K can be consumed through the diet from plant and animal sources. The normal flora of the intestine also produces vitamin K.
