Homeostasis works by creating the opposite effect in order to counteract a change in the body. One of these effects is blood coagulation. This means that blood is thickened and hardened in order to stop blood flow when there is a cut, open wound, or internal bleeding. Hemophilia on the other hand completely prevents blood from coagulating which makes the homeostasis process obsolete. Without blood coagulation, an individual can bleed to death from any small cut which is usually non-life-threatening.
