The CMY colours (commonly mistaken for Blue, Red and Yellow) are the answer when printing as mixing any two will form one of the darker RGB colours. The mix of all three CMY colours creates Black, although in practice this is very muddy.
White blood cells, like all blood cells are created in the bone marrow from certain stem cells. However, some lymphocytes are created but undeveloped or immature.
lymphocytes bone lymph nodes. The organs of the immune system either make the cells that participate in the immune response or act as sites for immune function.These organs include the lymphatic vessels, lymph nodes, tonsils, thymus, Peyer's patch, and spleen.The lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system. White blood cells (lymphocytes) that function in the immune response are concentrated in the lymph nodes.Lymphatic fluid circulates through the lymph nodes via the lymphatic vessels. As the lymph filters through the lymph nodes, foreign cells of microorganisms are detected and overpowered.he lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system.
