The causes of clotting deficiencies, including the types, genetics, and pathology of hemophilia. Introduction: Hemostasis is the process by which the body stops blood loss, and there are three major hemostatic mechanisms: spasm of blood vessels, formation of platelet plug, and clotting of blood. When an injury occurs, local blood vessels first constrict to reduce blood flow to the area; next, platelets adhere to the collagen fibers of the vessel wall exposed by the injury and release substances that further promote platelet aggregation and vasoconstriction such as serotonin, adenosine diphosphate, and thromboxane A 2 ; and subsequently, the coagulation of blood occurs. These mechanisms together help to stop blood loss. Blood coagulation itself consists of two pathways (the intrinsic and extrinsic mechanisms) that reach a common convergence point after following different steps. The common convergence point of the two pathways is reached when factor X is formed. This continues on to the end point, which is the formation of fibrin polymer molecules that form the blood clot. An absence of appropriate clotting, that is, a clotting deficiency, can occur due to a dietary insufficiency, a cancer such as leukemia, and also due to the presence of gall stones.
