 (rĭ-tĭk′yə-lō-ĕn′də-thē′lē-əl)
n.
The diffuse system of cells that destroy pathogens by phagocytosis, originally thought to include cells of the reticular tissues of the spleen, liver, bone marrow, and lymph nodes along with a variety of endothelial cells, all of which take up dye introduced into the bloodstream. This term has been largely replaced by "mononuclear phagocyte system" and restricted to the monocytes and macrophages.

[reticul(um) + endothelial.]

reticuloendothe′lial sys`tem


n.
the aggregate of the phagocytic cells that have reticular and endothelial characteristics and function in the immune system's defense against foreign bodies. Abbr.: RES
