Gangrene Causes, Symptoms and Signs

The causes of Gangrene are known. The first factor is the prevented blood supply. When a bloodstream faces some obstacles on its way to organs, the tissues of various parts stop obtaining enough blood. It spreads the oxygen over the body, delivers necessary nutrients and immune system elements to defend the organism from various dangers. The antibodies help to withstand different infections, and they depend on the bloodstream as well. It is impossible to survive without enough level of blood. That is why tissues start to die off.
