Final answer:
In North America, blood relatives are preferred as organ donors due to the belief in compatible blood types, while Japan values the harmonious aspect of receiving organs from family members. Immunosuppression is necessary in transplantation to prevent rejection.
Step-by-step explanation:
There are some differences between North American and Japanese beliefs regarding organ transplants. In North America, the preference for blood relatives as organ donors is influenced by the belief that they are more likely to have compatible blood types, reducing the risk of transplant rejection. Japan, on the other hand, places a strong emphasis on the concept of filial piety, where it is expected for children to care for their parents and the idea of receiving an organ from a family member is seen as more meaningful and harmonious.
Immunosuppression plays a critical role in transplantation by suppressing the recipient's immune system to prevent rejection of the transplanted organ. This is achieved through medication that inhibits the immune response. However, immunosuppression also poses challenges, such as increased susceptibility to infections and other side effects.
