 (2)Why may a person die quickly if the kidneyd fail to function?

 Thanks for answering my questions :)

Answer
1. The metabolism of fats takes much longer then that of a carbohydrate
2. The kidneys filter out wastes. If this is not done then the body chemistry is altered and cell damage occurs
3.The blood is passed through filters and the waste products are removed
4.With kidney failure body fluid is maintained and this can affect the lungs and all tissues. High protein food contain Nitrogen and nitrogen wastes are eliminated by the kidney
