<p>As the spleen removes antigens from the blood, lymph nodes remove antigens from tissue. Antigen presenting cells (B and T cells) migrate from peripheral tissue via afferent lymphatic vessels to the lymph nodes where they present their antigen to lymphocytes. B cells and T cells enter via the high endothelial venules by diapedesis and B cells migrate to the cortex while T cells to the deep cortex.</p>
