Why is organ transplantation challenging?

Question

Quizplus · Accepted Answer

The immune system's T cells can recognize and attack foreign tissue, even if it's from a donor, making it difficult for the recipient's body to accept the transplanted organ. Significant efforts are made to match the donor and the recipient's tissues as closely as possible to reduce the risk of rejection. Answer A is true, but not as directly related to the challenge of organ transplantation. Answer B is incorrect as identical twins are ideal donors since their tissues match closely, and the law does not prohibit them from donating to each other. Answer D is not entirely true, as organs can be harvested from living donors as well, and the minimum waiting period depends on the type of organ and the donor's condition.
