Reticuloendothelial system vs Mononuclear phagocyte system



Are these the same systems?

In: Biology

Google says they’re the same thing:

In immunology, the mononuclear phagocyte system or mononuclear phagocytic system (MPS) also known as the reticuloendothelial system or macrophage system

“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.[2]

Mononuclear phagocyte system, also called macrophage system or reticuloendothelial system

German pathologist Karl Albert Ludwig Aschoff introduced the term reticuloendothelial system in 1924, collating the cells based on their phagocytic activity. The later reclassification of phagocytic mononuclear cells, however, resulted in the exclusion of endothelial cells and fibroblasts

I’m not a doctor though, goodluck.
