Explanation:

Probably this answer won't add too much to the fiziology treties yet I guess that if the breathing system is functioning properly or not functioning at all, the exchange of Ccarbon dioxide/ oxigen wouldn't be possible ( at the heart level) and it would probsbly cause a heart strike.

Thinking of the function of the urinary system we might conclude that toxic substancies ( excretions) would not be separated to be ejected from the body and would probably keep settling in different parts/ organs causing disfunctions for the other systems

yes because there are aliens
