Asap explain well

Extracted text: The circulatory route through a lymphoid tissue for both immature B cells and mature B cells that do not encounter specific antigen is: O afferent lymphatic vessel → primary lymphoid follicle HEV of lymphoid cortex etferent lymphatic vessel O bloodstream afferent lymphatic vessel → HEV of lymphoid cortex -efferent lymphatic vessel. O bloodstream HEV of lymphoid cortex - primary lymphoid follicle -→ efferent lymphatic vessel O afferent lymphatic vessel -medullary cords→ primary lymphoid follicle -→efferent lymphatic vessel O primary lymphoid follicle HEV of lymphoid cortex -afferent lymphatic vessel →efferent lymphatic vessel
