what is the mononuclear phagocytic system
The mononuclear phagocyte system (MPS) (also called Reticuloendothelial System or Macrophage System) is a part of the immune system that consists of the phagocytic cells located in reticular connective tissue.The cells are primarily monocytes and macrophages, and they accumulate in lymph nodes and the spleen.ononuclear phagocyte system and monocyte macrophage system are two different terms, often mistakenly understood as one. Reticuloendothelial system is an older term for the mononuclear phagocyte system, but it is used less commonly now, as it is understood that most endothelial cells are not macrophages.
