  Hey Frizz
  
  It is very true! They are called Xenotransplant and it is as simple as transplanting a normal organ! You just have to make sure it is very similar and take special drugs so that your own body doesn’t fight against the new organ and reject it! A baboon heart has been transplanted into a human however shortly after it was rejected and unfortunately the person died! But with modern medicine I don’t think we’ll need to use animal organs! One day we might be able to grow our very own organs from our own stem cells!
  
  Hope that answers your questions! 🙂 Don’t forget to vote!
