Lymph Nodes Function as Meeting Points Between Antigen-Bearing Dendritic Cells

Lymph nodes function as meeting points between antigen-bearing dendritic cells arriving from the tissue and recirculating B and T lymphocytes. Whereas the dendritic cells coming from the tissue enter the lymph node via the afferent lymphatic vessels, the recirculating lymphocytes enter the lymph node:

A) Also from the lymph fluid draining the tissue
B) Directly from their primary lymphoid organ where they develop
C) From the blood by crossing the high endothelial venules
D) By being trapped in the lymphoid follicle by resident macrophages
E) By being carried there by dendritic cells
