Definition of Macrófagos

They are cells that belong to the immune system and are located in the different tissues of the body. Its name comes from the function they perform, which is to consume cells, bacteria and others, to defend the body.

From the Greek this word means “great dining room” and could be applied in different contexts. For example, it would be a synonym for glutton.


The word macrófagos is a Greek term that means “great eater”. From this perspective it could have different applications in the Spanish language. However, it is used almost exclusively to refer to cells of the immune system that “swallow” different particles to defend the body.

This term began to be used in biology since 1924, this was thanks to Aschoff. However, these particles were first studied by the Russian Ellie Metchnikoff in 1908 through a series of studies on immunity.


Macrófagos are formed in the bone marrow and are then distributed in the different tissues to contribute to the defense of the different organs.

The function of swallowing other bodies is called “phagocytosis” and it consists of eating the foreign bodies to protect the health of the body.
