Worked Solution & Example Answer:When a body organ is transplanted from one person to another, the immune system of the recipient is triggered - HSC - SSCE Biology - Question 26 - 2001 - Paper 1
Step 1
Patients who have an organ transplant are given drugs to suppress their immune response. State the reason for this.
Answer
The primary reason for administering immunosuppressive drugs to organ transplant recipients is to prevent the rejection of the transplanted organ. When a foreign organ is introduced into the body, the immune system recognizes it as a potential threat and mounts a response against it. By suppressing the immune response, these drugs help ensure that the recipient's body does not attack the transplanted organ, thereby increasing the chances of the transplant succeeding.
Step 2
Explain a possible consequence for the general health of organ transplant patients as a result of suppressing the immune system.
Answer
One possible consequence of suppressing the immune system in organ transplant patients is an increased vulnerability to infections. With a weakened immune response, the body is less capable of defending itself against pathogens such as bacteria, viruses, and fungi. As a result, transplant patients may experience a higher incidence of infections, which can lead to further health complications, prolonged hospitalization, or even severe illness. It is crucial for these patients to maintain a careful balance between immunosuppression and immune function to manage their health effectively.
