What is it about cold injury that kills the organs? could i ng term exposure cause organ necrosis and kill the victim?

GivinTheColdShoulder: Your question is a bit vague. But generally, if tissue is actually frozen (frostbite), water crystals form inside the cells and that messes-up the works. When thawed, the tissue is mush. If you are talking about hypothermia, the colder you get the slower your metabolism to the point that the lack of energy formation overcomes the overall slowness of the metabolic processes and then the cells die.
