Explanation:
Macrophages are a type of immune cells that function as phagocyte. They are produced by white cells called the monocytes. Upon ingestion of bacterial cells, cytotoxic compounds e.g cytokines are produced that digest the bacteria.
The macrophages are activated by the presence of microbes in the blood. They activate antigen T presenting cells to produce cytokines that further destroy the engulfed bacteria.
