Phagocytosis (from Ancient Greek φαγεῖν (phagein), meaning 'to eat', and κύτος, (kytos), meaning 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis.
Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell. In some forms of animal life, such as amoebas and sponges, phagocytosis is a means of feeding.
PHAGOCYTOSIS A three-stage process by which phagocytes (neutrophils, monocytes, and macrophages) engulf and destroy microorganisms, other foreign antigens, and cell debris.
Medical Definition of phagocytosis : the engulfing and usually the destruction of particulate matter by phagocytes that serves as an important bodily defense mechanism against infection by microorganisms and against occlusion of mucous surfaces or tissues by foreign particles and tissue debris Other Words from phagocytosis
Oct 04, 2019 · Phagocytosis, or “ cell eating”, is the process by which a cell engulfs a particle and digests it. The word phagocytosis comes from the Greek phago-, meaning “devouring”, and -cyte, meaning “cell”.
Essentially, phagocytosis may be described as a form of endocytosis through which a cell engulfs particulate matter/solid particles/cells. For different types of cells, phagocytosis plays a number of different roles ranging from food ingestion to the destruction of given cells and particulate matter.
Phagocytosis is a specific form of endocytosis by which cells internalise solid matter, including microbial pathogens. While most cells are capable of phagocytosis, it is the professional phagocytes of the immune system, including macrophages, neutrophils and mmature dendritic cells, that truly excel in this process.
Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it. The process of phagocytosis often happens when the cell is trying to destroy something, like a virus or an infected cell, and is often used by immune system cells.
Phagocytosis is the primary method used by the body to remove free microorganisms in the blood and tissue fluids. The body's phagocytic cells are able to encounter these microorganisms in a variety of ways Infection or tissue injury stimulates mast cells, basophils, and other cells to release vasodilators to initiate the inflammatory response.
Phagocytosis is an ancient adaptation. In primitive organisms, it is primarily used for the acquisition of nutrients [ 4 ], whereas, in higher organisms, it occurs in specialized cells (e.g., macrophages, DCs, and neutrophils) and is required for a wide variety of specialized biologic events.
