Doctors can now take a healthy kidney out of one person and put it into another, and most of the time it works. When it doesn't, the reason is the same thing that keeps you well.

Students will learn why the body can reject a transplanted organ, understand the problems that come with transplants, and then write and defend a position on whether organs should be donated or sold.
The immune system is the network in the body that fights infection, and it attacks anything it recognizes as foreign. Rejection is what happens when it does that to a transplanted organ. Doctors reduce the risk by matching the donor's organ to the patient, and by giving antirejection drugs that hold the immune system back.
The second problem is supply. There are far more people waiting for organs than there are donors, which is why some doctors have suggested paying donors, and why that suggestion is the argument at the end of the lesson.
🚨 This section is an ARGUMENT, not a drill. The book ends it with “You Decide!” and no answer key. Let the student reach a conclusion you disagree with, and then ask for the reason rather than correcting the conclusion.
The written task at the end is the point of the lesson. A paragraph with a clear position and two reasons is a better outcome than a perfect vocabulary score.
