Gran: have granules in their cytoplasm

Agran: lack granules

How is histamine similar to a call for help

It is released by basophils, calls other WBCs in for help when there is an infection

eosinophils

2-4 % of white blood cells

lymphocytes

25% of white blood cells

eosinophils

2-lobed nucleus

lymphocytes

2nd most numerous white blood cell

monocytes

3-8% of white blood cells

neutrophils

50-70% of white blood cells

neutrophils

lymphocytes

found in the lymph nodes

lymphocytes

have a large nucleus that takes up most of the cell

monocytes

have a kidney-shaped nucleus

lymphocytes

includes B cells

lymphocytes

includes T cells

monocytes

largest leukocytes

basophils

less than 1% of white blood cells

neutrophils

most numerous white blood cell

neutrophils

multi-lobed nucleus

basophils

rarest white blood cells

basophils

release an inflammatory chemical that attracts other white blood cells to the site of infection

basophils

release histamine

eosinophils

use enzymes to digest parasitic worms

neutrophils

use phagocytes to engulf bacteria

eosinphils

would target tapeworm or flukes
