Phagocytosis
Neurons do not typically carry out phagocytosis. Phagocytosis is a process by which certain immune cells engulf and digest pathogens or debris, and neurons are not specialized for this function. Microglial cells, which are a type of immune cell in the brain, are responsible for phagocytosis in the central nervous system.
Phagocytosis is a process where immune cells engulf and digest foreign particles, such as bacteria or viruses, to eliminate them from the body. It is a part of the nonspecific immune response, carried out primarily by macrophages and neutrophils. In the context of specific immunity, phagocytosis plays a role in presenting antigens to lymphocytes to initiate a more targeted immune response.
White blood cells, particularly macrophages and neutrophils, use phagocytosis as a mechanism of defense against invading pathogens. These cells engulf and digest foreign particles such as bacteria, viruses, and cellular debris to protect the body from infections.
No per Marieb. Basophils just release histamine and mediators of inflammation and they also contain helarin. Lymphocytes mount immune response by cell attack or via antibodies. The rest do phagoctytize.
Neutrophils are cells that do not absorb either an acidic or basic dye and consequently are a purplish color. They are also called phagocytes because they specialize in phagocytosis and generally combat bacteria in pyogenic infections.
Benefits of phagocytosis include the removal of pathogens and debris from the body, helping to prevent infections and maintain tissue health. Drawbacks may include potential inflammation and damage to healthy tissue if the immune response is excessive or dysregulated.

phagocytosis
Cell eating refers to the process of phagocytosis, where cells engulf and digest particles like bacteria or cellular debris. This mechanism helps in immune defense and nutrient acquisition in cells such as macrophages and neutrophils.
The defense function of the body is called the immune system. It is responsible for protecting the body against foreign invaders such as bacteria, viruses, and other harmful pathogens. The immune system comprises a network of cells, tissues, and organs that work together to defend the body.
The primary role of phagocytes is the ingestion and destruction of invading icroorganisms. This process called phagocytosis is acheived in part through a respiratory burst that results in the generation of reactive oxygen species (eg: superoxide, hydroxy radical, hydrogen peroxide, hypochlorous acid) mediated by the activity of a membrane-bound NADPH-dependent oxidase system.
