The theme of this paper is Marketing Elements of the Market for Human Organs. The organ is a part of the human body formed by different tissues that has a special function. Sometimes, due to various harmful circumstances for the human body, the organ ceases to perform its function and needs to be replaced by a new one. Organs are donated to patients after a particular organ is listed on the Eurotransplant list, that is, on the lists of the non-profit European organ exchange organization. Organs are obtained in such a way that a donor, or a person who has declared during a lifetime that he or she wishes to donate an organ, donates the organ during life or after death. In the absence of organs, certain patients wait on the list until a compatible organ appears for them. Some patients never receive an organ because the waiting lists are too large compared to the offer on the market. Due to the above facts, there is a need for illegal organ trafficking, i.e. demand or supply of organs on the black market. The situation in the world is very serious; many people talk about the topic of black market because it is a problem that has been present for many years). Some studies show that about 10% of all transplants performed annually in the world are organ transplants from living donors through illegal organ trafficking. Although a large number of people are on the waiting list in the Republic of Croatia, the topic of organ procurement from the black market is not something that is often mentioned.
