What about people with Diabetes? They cannot survive on their own and must take insulin shots. Is that not superseding the original function of the Pancreas? Not to mention that mechanical pancreases might soon be a thing, as well as pig-to-human heart transplants. You have a really strict idea of what a human is, IMO.

Does DNA you have match up with that of humans?
This is one of a whole raft of philosophical questions about vague terminology. Other more important examples include "when does a foetus become a human being?", "how can you get life from non-life?" and "what is the moment of death?" (along with the classic "how many stones make a heap?")
All these problems essentially boil down to one issue which is that words purport to divide the world into clear categories, but actually all words have some degree of vagueness about the edges. We have to accept that at some stage, there were creatures that were not human, and at some stage there were creatures that were, and in between there were creatures that were 'quite' human.
Similarly, a person with a mechanical heart is still a human being, but they are marginally less human than they were before. As the Tin Man replaced more and more pieces, he became less human and more robot. For some reason people find this idea problematic, but it's always seemed simple enough to me. As I say, it's pretty hard to think of *any* word that has a truly unambiguous clear-cut definition.
