Although the immune system is affected by the aging process, the elderly are not the only individuals who have autoimmune disorders. These occur in populations of all ages because autoimmune disorders involve:
A) An attack of antibodies on body cells
B) An overproduction of T cells in bone marrow
C) A decrease in the weight of the thymus gland
D) An increase in the amount of lipofuscin in the blood
A
Feedback:
In autoimmune disorders, the immune system attacks and destroys the body's own cells (as opposed to those of invading, disease-causing microorganisms). There is no overproduction of T cells. Although the weight of the thymus gland decreases with age and the amount of lipofuscin increases, such changes are not characteristic of autoimmune disorders.
