Degree paper discusses justice at organ donation and allocation. It tells us, how do current ways and systems consider rights of donors, the medical staff and recipients. It shows, on which areas we have to be especially careful, so it doesn't come to any abuse. At the beginning, it concentrates on Eurotransplant organization, which takes care of allocation of organs in certain countries of Europe, including Slovenia. After that, it describes the ETKAS system, which is used to allocate donated kidneys, grading system of potencial recipients and how do they take care of patients with high urgency status and kids. Afterwards it describes other systems and ways used at organ donation. Firstly, the reward system is introduced, how do people in Germany, South Korea and Sweden react to it and how does it influence the valuing of the human body. After that, altruism, reciprocity and solidarity are described. Those three concepts represent the core of what organ donating really means and the main reason, why people should donate. In the next part, the unjustice actions correlated with organ donation are shown. This includes the process of organ donation after euthanasia, which mostly happens in Belgium and Netherlands. Besides that it describes the im/possibility of prisoners donating organs in the USA and in China, also showing what kind of attitude they have towards it.
