phagocytosis
Term: phagocytosis
Literally meaning: "the eating of cells"
Origin: Anc Greek
?????/phagos(=eater) > ??????/ephagon(=indefinite tense of verb "?????"/esthio(eat, devour)
+cyte(=combining form meaning ?cell? derived from anc Greek word ??????/cytion (=box, container)
=-????/-osis(=suffix denoting usually a procces )
Coined/History
In 1882 by Russian zoologist Ilya Ilyich Mechnikov (1845-1916) described the specialized cells that were involved in the defense against microbial infections and after sharing his findings with Carl Friedrich Claus (Vienna) he named them "phagocytes". Mechnikov, a year later added the term "phagocytosis" concerning all the procces of engulfing pathogens by these cells.
Definition
Phagocytosis is the cellular process which is used by cells of immune system in order to engulf and indigest solid particles as microorganisms and cellular debris.
