Most abundant white blood cell., The most abundant type of white blood cell. Phagocytic and tend to self-destruct as they destroy foreign invaders, limiting their life span to a few days. 40-60% of WBC.
Lymphocytes
A type of white blood cell that make antibodies to fight off infections. There are 3 types: T Cells, B Cells, and NK Cells.
Monocytes
*A type of white blood cell that transforms into macrophages, extends pseudopods, and engulfs huge numbers of microbes over a long period of time. Stored in Spleen and moves in blood to infected tissues. 0-7% of WBCs.
Eosonophils
Releases toxins that kill bacteria and parasites but also causes tissue damage. Circulates in blood and migrates to tissues. 0-.3% of WBCs.
Basophils
A circulating leukocyte that produces histamine. 0-1% WBCs.
Never Let Monkeys Eat Bananas
Neutrophils, Leukocytes, Monocytes, Eosinophils, and Basophils.
ADAPTIVE IMMUNE SYSTEM
the third layer of defense in the immune system that's composed of highly specialized, systemic cells and processes that eliminate or prevent pathogen growth
AGRANULOCYTES
white blood cells that contain no granules; the agranulocytes include the lymphocytes and monocytes
ANAPHYLAXIS
