... Approximately 3x1011 lymphatic cells flow through the system on a given day. A similar number are processed through the spleen. This high flux of cells insures that a foreign antigen will meet the appropriate B and T cells within a short period of time. If the naive lymphocyte does not encounter an ...

Lymphopoiesis
Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cell (WBC). It is more formally known as lymphoid hematopoiesis.Pathosis in lymphopoiesis leads to any of various lymphoproliferative disorders, such as the lymphomas and lymphoid leukemias.
