Question

40 multiple choice 10 points a recipient of a transplant faces an elevated risk of organ rejection when there is not a close match between the recipient and the donor in terms of which of the following? major histocompatibility complex antibody response sex and age race

Explanation:

The major histocompatibility complex (MHC) is crucial in organ - transplant compatibility. If there is not a close match in MHC between the recipient and the donor, the recipient's immune system is more likely to recognize the transplanted organ as foreign and mount an immune response, leading to organ rejection. Antibody response can be related to rejection but is secondary to MHC matching. Sex, age, and race are not the primary factors determining the risk of organ rejection in terms of tissue - matching.

Answer:

A. Major Histocompatibility complex
