phagocytes White blood cells that can engulf (by phagocytosis) and destroy microorganisms including viruses and bacteria; cells in this category include neutrophils and monocytes.
Phagocytes ("phago-"=eating, "cyte"=cell) migrate to affected areas and engulf pathogens. Neutrophils and macrophages are phagocytic white blood cells. This migration of white blood cells causes the redness and inflammation associated with infection.
phagocyte Any cell that engulfs and devours microorganisms or other particles.
phagocytosis The engulfment of a particle by a phagocyte or a protozoan.

Phagocytes utilize an NADPH oxidase to generate large amounts of ROS, and exploit their toxic properties as a host-defence mechanism to kill invading microbes.
Human neutrophils are white blood cells that serve as professional phagocytes: their primary function is to eat and kill bacteria and they arrive quickly at the site of a bacterial infection.
The process of engulfing and ingestion of particles by the cell or a phagocyte (e.g. macrophage) to form a phagosome (or food vacuole), ...
Using phagocytic cells, like macrophages and neutrophils, to gain entry into the internal environment is a risky strategy because phagocytes are poised to destroy engulfed bacteria.
An important part of the mononuclear phagocyte system, make up of lymphoid tissue. It stores excess red blood cells, destroys old cells, and is capable of acting as a reservoir holding 20-30% of all blood cells.
Pseudopods also capture prey phagocytosis. Phagocytosis pseudopods have arisen in a number of different protist groups, but also in some cells (phagocytes) in multicellular organisms.

Clumping makes the job of phagocytes easier, as they will more readily engulf bacteria in clumps. Bound antibodies sometimes serve as tags, called opsonins, enhancing phagocytosis.
The T cells secrete proteins that punch holes in the infected cell's plasma membrane. The infected cell's cytoplasm leaks out, the cell dies, and is removed by phagocytes. Killer T cells may also bind to cells of transplanted organs.
The specialized cells in our blood are the red blood cells (rbcs) containing the respiratory protein, hemoglobin, to carry gases, the white blood cells (e.g., phagocytes, lymphocytes) which fight infection and the blood platelets which upon ...
