Necrosis Caused by Ischemia

Necrosis caused by ischemia is the death of body tissue by lack of oxygen-rich blood supply, due to occlusion (blockage) of one or several blood vessels or to exposure to extreme low temperatures, since cold weather makes small arteries and veins to contract, blocking the blood flow. What causes death of tissue cells are the lack of oxygen and glucose carried by arteries.
