Xenotransplant
Xenotransplantation
Xenotransplantation (pronunciation: /ˌzenəˌtransplɑːnˈteɪʃən/) is a medical procedure that involves the transplantation, implantation or infusion of cells, tissues or organs from one species to another.
Etymology
The term "xenotransplantation" is derived from the Greek word "xenos", which means stranger or foreigner, and the Latin word "transplantare", which means to move from one place to another.
Definition
Xenotransplantation is a form of organ transplantation where the donor and recipient belong to different species. The most common form of xenotransplantation is from animals to humans, known as zoonotic transplantation.

Risks and Ethical Considerations
