Xenotransplantation is the process of transplanting organs, tissues, or cells from one species to another. This practice is primarily used in the field of medicine to address the shortage of human organs available for transplantation. For example, pig organs have been considered a potential source of organs for human transplantation due to their similarities in size and function to human organs. However, challenges such as organ rejection and transmission of diseases from animals to humans must be carefully considered and addressed in xenotransplantation research. Ultimately, the goal of xenotransplantation is to provide a viable and ethical solution to the organ shortage crisis in the medical field.
