ANS: D. Generative (primary) lymphoid organs are the organs where lymphocytes first express
V V V V V V V V V V V V
antigen receptors and attain functional maturity. Although T cell precursors arise in the bone marrow,
V V V V V V V V V V V V V V V
these precursors migrate to the thymus, where maturation takes place. In contrast, B cells mature in the

ANS: B. Many tissue-resident macrophages are derived from fetal yolk sac and fetal liver precursors
V V V V V V V V V V V V V V
and establish residence in the different tissues during fetal development. Other tissue- resident
V V V V V V V V V V V V V
macrophages are derived from bone marrow–derived blood monocytes that enter tissues under
V V V V V V V V V V V V
normal conditions or during infections. Epithelial cells do not differentiate into macrophages. Once in
V V V V V V V V V V V V V V
the tissue, tissue-resident macrophages cells do not leave to recirculate. Naive T cells do not usually
V V V V V V V V V V V V V V V V
enter non-lymphoid tissues, and tissue-resident macrophages have no role in presenting antigen to

ANS: A. Classical (or conventional) dendritic cells (DCs) are the main cell type that brings microbial

antigens from infected tissues into draining lymph nodes and presents peptides derived from these
V V V V V V V V V V V V V V

interferons in response to viral infection. Plasma cells are antibody-secreting cells derived from B cells
