Monocytes circulate in the bloodstream as they enlarge, before migrating into different tissues and differentiating into specific tissue macrophages. How long do the monocytes circulate for?

How much do monocytes enlarge by in the circulation before migrating to the tissues?

Macrophages which take up residence in specific tissues are called fixed macrophages. What is the name of the macrophages that remain motile and travel via amoeboid movement throughout the tissues?

Macrophage-like cells serve different functions in different tissues and are named according to their tissue location. List some tissue-specific macrophages.

Activated macrophages (by antigen phagocytosis, complement, antibody, or TLR interaction with PAMPs) are more efficient at eliminating potential pathogens than inactivated macrophages. How so?
