You actually do have organ backups.

  If you have a second heart, please report to area 51 immediately

    That would be Krogan, not me. There are animals with multiple hearts. People can be made to have 2 hearts too, but let me not go into that. But we have bunch of non-heart redundancy.

      Yeah, if you ignore the various single points of failure in our circulatory, digestive and nervous systems there are plenty of redundancies. There is no intelligence behind our design. Your body takes its current form because no mutation which would change it has yet led to a statistically greater chance of you passing on your genes. That nature designed you to have pain receptors is no more an argument for their utility than it is for the peacock's feathers.
