Neutrophils: White blood cell that first responds to infections inside the body. They are able to kill foreign materials in the body without specifically identifying what type of foreign material is in the body.

Neutrophils are part of the innate immune system.

Basophils:  Non-phagocytic white blood cells that secrete histamine and heparin. They have a multi lobed nucleus and increase in numbers during an allergic response.

Basophils induce vasodilation.

Eosinophils: White phagocytic cells that are motile. There are about 1-5% of these white blood cells.

Eosinophils can expel granules into extracellular space.
