Question

Quizplus · Accepted Answer

A severe immune reaction can occur in response to a blood transfusion if the blood type of the recipient is incompatible with the donated blood. This can result in a transfusion reaction, which can be life-threatening in some cases. However, this type of reaction does not cause an immunodeficiency, which is a condition where the immune system is compromised and unable to properly defend against infections. Inherited lack of B cells (A) can result in a type of immunodeficiency known as X-linked agammaglobulinemia (XLA). Surgical removal of the thymus (C) can also result in immunodeficiency, as the thymus is important for the development of T cells. SCID (D) is a type of severe combined immunodeficiency, where both T and B cell function are impaired. AIDS (E) is a viral infection caused by HIV, which specifically targets and damages the immune system, leading to immunodeficiency.
