What is the difference between a devouring cell and a phagocyte?
They appear to be more or less specific, a separate opsonin being necessary for phagocytosis of each species of bacteria. Hence the names phagocyte, or devouring cell, given to the enveloping white globule, and phagocytosis to the process. There are two conditions, under normal circumstances, in which phagocytosis plays a marked part.
