ABSTRACT
Hemostasis governs two essential processes of human life in that it maintains the
fluidity of blood under physiological conditions and prevents excessive blood loss
after injury. Hemostasis is regulated by components of the vessel wall and blood cells
and by humoral coagulation factors. Under normal conditions, these components are
involved in an active equilibrium through activation, propagation, and termination
of the hemostatic pathways. This equilibrium is disturbed upon vascular injury, leading
to a procoagulant response when needed. Unfortunately, pathological disturbances can
occur as a result of inherited or acquired coagulation factor deficiencies that may
lead to bleeding or thrombotic disorders.
