Spleen: You can think of the spleen as a filter for the blood. It catches foreign material in the blood and activates different types of immune system cells.

Lymph Nodes: The lymph nodes filter foreign material from the lymph fluid. Fluid that drains from various tissues in the body collects in the lymph system and passes through the nodes, being filtered as it passes.

T-Cells: There are two subsets of T-cells: CD4 cells and CD8 cells. CD4 cells secrete factors that activate other white blood cells that participate in the immune response. HIV attacks CD4 cells, damaging the body's ability to initiate the immune response. CD8 cells are important in directly killing tumor cells, viral infected cells and some parasites.
