The Immune System Normally Discriminates Between __________ Antigens

Question

The immune system normally discriminates between __________ antigens.
A)self and nonself
B)B and T cells
C)humoral and cell-mediated
D)primary and secondary response

Accepted Answer

The immune system is designed to distinguish between self and nonself antigens. Self antigens are antigens found in the body's own cells and tissues, while nonself antigens are foreign to the body and can trigger an immune response. This discrimination is essential to prevent the immune system from attacking the body's own cells and tissues, which can lead to autoimmune disorders.
