Blodudsivning in, or just under the skin will appear as abruise. Normally, the bleeding stop in a short time because the blood's ability to clot (clot).

Koagulation (clotting):Størkningsprocessen is a collaboration between coagulation factors (enzymes in the blood that control blood clotting), the blodkarvæggen and circulating platelets (platelet) in the blood. The damage to the tank, there is only a contraction of the tank, so that the amount of blood in the leaking area reduced. Next, melt the platelets fixed to karvæggen over the leaks. Finally enclosed platelets of a substance called fibrin, which forms a trådagtigt material for

A bleeding can occur anywhere in the body and may have different reasons, including:

  • Mechanical damage to a blood vessel:If the body inflicted a blow, plug or cut, it can lead to a bristning of blood vessels.

  • Inborn haemophilia:In the case of mutations (errors) koagulationsfaktorerne as evidenced by haemophilia stop størkningen because of the lack of coagulation factors important to the process. This also means that people suffering from haemophilia have a greater tendency to bleeding.

  • By alack of platelets ( thrombocytopenia )there is not enough platelets in the blood to stop a hemorrhage. People suffering from thrombocytopenia, has increased bleeding tendency.

  • Aincreased activity of the system breaking down fibrin(trådagtige material over the platelets) provide major bleeding tendency.

Some medicines can give fragile blood vessels, and therefore increased tendency for bleeding. This is especially true binyrebarkhormon (kortison, prednisolone).
