Of or pertaining to phagocytes or phagocytosis. Phagocytosis (from Ancient Greek Ïαγεá¿Î½ (phagein) 'to eat', and κÏÏοÏ, (kytos) '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. They bind to pathogens and internalise them in a phagosome, which acidifies and fuses with lysosomes in order to destroy the contents. A phagocyte is a type of white blood cell. Of or relating to phagocytes. Phagocytosis, or â cell eatingâ, is the process by which a cell engulfs a particle and digests it.

There are also a number of other cells that act as partial phagocytes, meaning that they serve other functions throughout the body, but ⦠Phagocytic cells usually involve in the first line defense by the immune system in response to acute microbial diseases and leads to inflammation [32]. Phagocytosis is the process of taking in particles such as bacteria, parasites, dead host cells, and cellular and foreign debris by a cell. B lymphocytes (B cells) ...
