 | | In the marrow, the neutrophils exist in 2 divisions—the proliferative, or mitotic, compartment (myeloblasts, promyelocytes, myelocytes) and the maturation-storage compartment (metamyelocytes, bands, polys). |
 | | Some neutrophils do not circulate freely (marginal compartment) but are adherent to the vascular surface, and these constitute approximately half the total neutrophils in the blood compartment. |
 | | Neutrophils leave the blood pool in a random manner after 6-8 hours and enter the tissues, where they are destined for cellular action or death. |
