Which blood cells eat bacteria and other microorganisms by phagocytosis?

Explanation:
Phagocytosis is the process by which certain immune cells engulf and digest invading microbes. Monocytes circulate in the blood and can engulf bacteria and other microorganisms; when they migrate into tissues, they become macrophages, which are highly effective at phagocytosis and also help present pieces of pathogens to other immune cells. Lymphocytes are mainly involved in targeted, adaptive immune responses and are not primarily phagocytes. Erythrocytes carry oxygen, and platelets are involved in clotting, not ingestion of microbes. Therefore, the blood cells that eat bacteria by phagocytosis are monocytes.
