	Amount in human blood	Diameter	Life span
Neutrophil	50-70%	10-12 µm	Normally three to four days; less than 12 hours after digesting invaders
Eosinophils	1-3%	12-15 µm	Three weeks
Basophils	0.4-1%	12-15 µm	Three days to one week
Lymphocyte	25-35%	small :6-8 µm large: 8-12µm	B cells: four days to up to five weeks T cell: month to years
Monocyte	2-8%	20-30 µm	10-20 hours
