In general, the response of the leukocytes to
chemotaxis is a conservative process. Chemotaxis means simply the effect of the presence of certain substances on vital organisms without specific chemical action. Chemotaxis alone will not explain the continuance of leukocytosis for more than a short time.
Non-phagocytic leukocytosis is probably due more to stimulation of blood-making organs than to
chemotaxis. British Dictionary definitions for chemotaxis noun the movement of a microorganism or cell in response to a chemical stimulus Derived Forms chemotactic, adjective chemotactically, adverb
