4. Causes of Gangrene  Our cells require nutrients delivered to them by blood. If this blood supply becomes low they will become damaged and die.  When blood flow is restricted to the affected area no white blood cells or t-cells are able to get to it and help prevent the disease from spreading

5. How to cure Gangrene  Antibiotics  Maggot therapy Maggots and fly larvae feed on the dead infected tissue  Blood Transfusions  Surgery Removal of the affected area helps prevent disease from spreading

6. Worst Case Scenario  If left untreated gangrene will spread to other body parts and death will eventually occur.
