ie, if every cell is constantly replaced wouldn’t the organ eventually be replaced by your own cells that your isn’t trying to kill?

I think eventually is the operative word. Theybsay it takes 7 years to replace all cells give or take, its not actually teue as depends on cells etc

Long time to wait without a heart

Also the cells arent made elsewhere in the body and then deposited tonsay where the heart is, theyre made inside the heart which is continously renewing themselves, so a donar heart would just make the same cells and not “your” cells as it were.
