Q

Which cell is a connective tissue macrophage?
a. Kupffer cells
b. Histiocyte
c. Dust cell
d. Langerhans cell
e. Microglia

A

b. Histiocyte

Macrophages are mononuclear phagocytes. Many tissues have resident (fixed) macrophages. Fixed macrophages are given a unique name, depending on the tissue that they are located in.
Kupffer cells are the hepatic macrophages.
Histiocytes are macrophages seen in connective tissue.
Dust cells are alveolar macrophage found in the respiratory tract.
Langerhans cells are macrophages seen in the skin.
Microglia are the central nervous system macrophages.
