It is a large white blood cell that is an important part of our immune system.
Macrophages. The macrophage is a vital type of white blood cell. A macrophage is a kind of swallowing cell, which means it functions by literally swallowing up other particles or smaller cells. Origin. Macrophages come from specific white blood cells called monocytes. Monocytes are born from stem cells in the bone marrow and circulate throughout the blood stream. Once a monocyte leaves the blood, it matures into a wandering macrophage or a fixed macrophage. Macrophages are a type of white blood cells that engulf foreign material. They are key players in the immune response to foreign invaders, such as infectious microorganisms Macrophages also release substances that stimulate other cells of the immune system. This information is based on source information from the National Institute of Neurological Disorders and Stroke. Macrophage. First on the scene. Macrophages, a kind of white blood cell, are the first cells at the scene of infection, and they get there from your blood. Your blood looks like it is just a red fluid but it has lots of other kinds of cells too A macrophage is a large white blood cell that is an important part of our immune system. The word 'macrophage' literally means 'big eater.' It is an amoeba-like organism and its job is to clean our body of microscopic debris and invaders. A macrophage uses a process called phagocytosis to destroy and get rid of unwanted particles in the body. Phagocytosis literally means 'eat cell.' The process works like this: as the macrophage engulfs the particle, a pocket called a phagosome is formed around it. macrophage. any of the large, mononuclear, highly phagocytic cells derived from monocytes, occurring in the walls of blood vessels (adventitial cells) and in loose connective tissue (histiocytes, phagocytic reticular cells). They are components of the reticuloendothelial system. macrophage. any of the large, mononuclear, highly phagocytic cells derived from bone marrow cells, promonocytes, the progeny of which, the monocytes, enter the bloodstream, where they stay for a few days before entering the tissues and developing into macrophages. Macrophage: A type of white blood cell that ingests foreign material. Macrophages are key players in the immune response to foreign invaders of the body, such as infectious microorganisms. They are normally found in the liver, spleen, and connective tissues of the body. Macrophages are a type of white blood cell which eat foreign material in the body. These cells are involved in the primary or innate immune response to a number of immune invaders, and they also make up an important part of the body's acquired immune system. Macrophages help clean up bacteria and viruses in the body. Macrophages can be co-opted by HIV cells and aid the spread of the virus. A monocyte is the first stage of life for a macrophage. Macrophages are a type of white blood cell that eats foreign material in the body. Phagocytes dispose of cells that have undergone apoptosis, or programmed cell death Medical Definition of MACROPHAGE. : a phagocytic tissue cell of the immune system that may be fixed or freely motile, is derived from a monocyte, functions in the destruction of foreign antigens (as bacteria and viruses), and serves as an antigen-presenting cell—see histiocyte, mononuclear phagocyte system. Definition of MACROPHAGE. : a phagocytic tissue cell of the immune system that may be fixed or freely motile, is derived from a monocyte, functions in the destruction of foreign antigens (as bacteria and viruses), and serves as an antigen-presenting cell — compare histiocyte. — mac·ro·phag·ic \ˌma-krə-ˈfa-jik\ adjective.
