Q
MP development into a resident monocyte by stage
A
Hemopoietic Stem Cell –> Granulocyte/Monocyte-colony forming unit (GM-CFU)—> M-CFU influenced —> monoblast –> pro-monocyte —> inflammatory monocyte —> resident monocyte

Q
Monocyte/Macrophages by tissue:
Lung Liver Connective tissue Spleen Bone CNS
A
lung = alveolar macrophage
liver = kupffer cell
connective tissue = histiocyte
spleen = white pulp macro, marginal zone macro, metallophilic macro
CNS = microglial cell Bone = osteoclast
