mac·ro·phage

(măk′rə-fāj′)
Any of the large white blood cells in many vertebrates that engulf and break down foreign particles and bacteria in blood or lymph. Macrophages are important in the body's defense against disease and are found mainly in the spleen, lymph nodes, and liver.

Following the discovery of phagocytic cells by Ilya Ilyich Mechnikov in 1882 these cells had been called clasmatocytes, polyblasts, reticular cells, and other terms: today we designate them as macrophages or histiocytes.
Dutra (1948) noted that in some cases, clasmatocytes (macrophages) could be seen surrounding fibrinoid material in alveoli, and these cells were sometimes fused to form multinucleated giant cells; others also noted occasional giant cells (Freiman and Hardy 1970).
It is believed that the sources of the mononuclear exudate cells are, on the one hand, the "resting wandering cells" of Maximow(6) [the "clasmatocytes" of Ranvier, the "histiocytes" of Aschoff and Kiyono(7) and Kiyono(8)]; on the other hand, the endothelium of the common blood vessels, to which an important r61e is attributed.
