Post-capillary venules are the smallest of the veins with a diameter of between 10 and 30 micrometres (μm). When the post-capillary venules increase in diameter to 50μm they can incorporate …

WebLymphocytes recognise and adhere to these endothelial cells, and squeeze through them into the deep cortical regions of the nodes. This region of the lymph has lots of T-cells, as well as the antigen presenting dendritic cells. T-cells entering here become activated in the cortex, between lymphoid follicles. show labels. High endothelial venules (HEV) are specialized post-capillary venules characterized by plump endothelial cells as opposed to the usual flatter endothelial cells found in regular venules. HEVs enable lymphocytes circulating in the blood to directly enter a lymph node (by crossing through the HEV). In humans, HEVs are … Ver mais In order to have an adaptive immune response occur, T cells need to be activated.
