RESIDENT CELLS – MACROPHAGES -2
Lymph nodes are small organs scattered throughout the body through which lymph passes. In the lymph nodes, lymph is “filtered” by macrophages, as they have the opportunity to encounter antigens carried by the lymph, destroy microorganisms, and trigger an immune response.
In the figure, the arrows point to macrophages located within a lymph node.
Note that the cytoplasm of one of the macrophages appears to be “foamy” or vacuolated. This is likely due to the large number of vacuoles in its cytoplasm.
Phagocytosed material will be highlighted in light blue after placing the cursor or clicking on the figure.
