IMMUNE SYSTEM FUNDAMENTALS AND

CELLULAR PROLIFERATION

The myeloid progenitors develop into the cells that respond early and nonspecifically to infection.

Neutrophils engulf bacteria upon contact and send out warning signals.

Monocytes turn into macrophages in body tissues and gobble up foreign invaders.

Granule-containing cells such as Eosinophils attack parasites.

Basophils release granules containing histamine and

other allergy-related molecules.
