3. Recently, a human trachea (a respiratory organ) was produced by using a patient's own stem cells.
The benefit of using the patient's own cells to produce a trachea instead of receiving one from a
donor is that

(1) there will be more enzymes produced to help maintain homeostasis in the trachea
(2) there will be an increase in the quantity of antibodies that the patient produces in
response to the new trachea
(3) there is less of a chance that the patient's immune system will attack the trachea
(4) there will be a greater response to any infectious agent that may enter the body
