Not long ago, people regularly died from diseases and accidents that harmed their vital organs, but in the space of the last six decades, scientists have begun to successfully perform lifesaving organ transplants. Over this relatively short period of time, the field of organ transplantation has made monumental gains. This book examines the science that led up to the first organ transplant and explores the lives of the scientists who played a role in this discovery. It also outlines the different types of transplants, including cross-species transplants. Finally, through discussions on ethical issues and technology, students will be encouraged to critically examine where science is going in the future of organ transplants.
