If one part of your body system fails to carry out its function properly, then other body systems are affected since the body systems are connected with each other. One system is very important that is why if one fails others are affected. If this one system is a very important one, then it may lead to death, if this one system is not that very important, then it can affect other body systems, which in turn, may not function properly anymore which can lead to a slow death.
