white blood cell

n. Abbr. WBC
Any of various cells that in adult mammals are produced in bone marrow, have a nucleus but no hemoglobin, and function in the immune system by protecting against pathogens and aiding in tissue repair. White blood cells include neutrophils, eosinophils, basophils, lymphocytes, and monocytes, and they are found in blood, lymph, and certain tissues. Also called leukocyte, white cell, white corpuscle.

white blood cell

n
(Biochemistry) a nontechnical name for leucocyte

n.
any of various nearly colorless cells of the immune system that circulate mainly in the blood and lymph, comprising the B cells, T cells, macrophages, monocytes, and granulocytes. Also called leukocyte , white′ blood′ cor`puscle, white′ cell`.

white blood cell

(wīt)
Any of various white or colorless cells in the blood of vertebrate animals, many of which act to protect the body against infection and to repair tissues after injury. White blood cells have a nucleus, unlike red blood cells, and are formed mainly in the bone marrow. The major types of white blood cells are granulocytes, lymphocytes, and monocytes. Also called leukocyte.
