Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why must donated tissue be analyzed before it is transplanted into another person?
A
to prevent the recipient’s body from attacking and rejecting the tissue as foreign
B
to eliminate the introduction of pathogens into the recipient
C
to prevent the recipient’s red blood cells from clotting
D
to prevent the formation of antigens in the donated tissue
Explanation: 

Detailed explanation-1: -This is because the person’s immune system detects that the antigens on the cells of the organ are different or not “matched.” Mismatched organs, or organs that are not matched closely enough, can trigger a blood transfusion reaction or transplant rejection .

Detailed explanation-2: -After an organ transplant, you will need to take immunosuppressant (anti-rejection) drugs. These drugs help prevent your immune system from attacking ("rejecting") the donor organ. Typically, they must be taken for the lifetime of your transplanted organ.

Detailed explanation-3: -The risk of infection is increased after a transplant because of immunosuppressive medicines. These medications keep your immune system from attacking the new organ, but they lower your body’s ability to fight infections. It’s important to take steps in your daily life to prevent infection.
