Final answer:
The harvesting of kidneys for transplantation can only be from living donors.
Step-by-step explanation:
The statement that harvesting of kidneys for transplantation can only be from living donors is true.
Kidneys are commonly harvested from living donors through a surgical procedure called a nephrectomy. The donor must undergo thorough evaluation to ensure compatibility and good health before the transplantation can proceed. This is because a living donor kidney has a higher chance of success and can provide an immediate solution to the recipient's kidney failure.
