    In a previous video, you explained that B-cells need to be activated in order for them to release the antigen, which will bind the virus/bacteria. But how will the B-cell become activated, if they stay inside the lymph node? Thanks!

      if you found out the answer do tell please. i guess not only macrophages go to lymphatic system, pathogens too

      B and t cells are made in bone marrow and thymus respectively. They both need to profilerate or become mature at secondary lymphoid organs....ie they get activated by the antigens present in the lymph nodes,malt etc.

      @@Medicoboi I think T cells are made in bone marrow too. They just mature in thymus

      I thought T cells are produced in the spleen & lymph, but mature in the thalamus.

    How will the Macrophage, know what the nearest lymph node is, and if so, is there a possibilty that the right B Cell won't be there?

    With regards to the transport process of the neutrophils having to squeeze through the epithelium and that transport itself you said is 'active transport', would that mean the layer of epithilium is classified as simple columnar epithilium? Because there is no need for cellular energy to transport through simple squamous epithilium?.....
