Phagocytes kill pathogens by engulfing them.
hope that's helped!
Macrophages are a type of phagocyte that engulf damaged cells or pathogens that have entered the body's tissues. They play a vital role in the immune response by removing these foreign substances and initiating the inflammatory process.
A large phagocyte that engulfs other cells and is found in lymph nodes and tissues is called a macrophage. Macrophages play a key role in the immune response by engulfing and digesting pathogens, dead cells, and debris to help maintain tissue homeostasis and promote immune defense.
A cell that engulfs another cell is known as a phagocyte. Phagocytes are a type of white blood cell that engulf and digest foreign particles, such as bacteria or dead cells, through a process called phagocytosis. This process helps the immune system to remove pathogens and cellular debris from the body.
Phagocytosis is the process by which a cell engulfs matter and packages it into an internal vesicle. Pinocytosis is the same process but for a liquid. Collectively these can be referred to as endocytosis. A type of human white blood cell called a phagocyte uses phagocytosis to ingest bacteria, toxins and other pathogens and delivers them to lysosomes (membrane bound vesicles of digestive enzymes). The phagocyte then undergoes autophagy (self digestion) and dies, during infection the build up of these dead cells gives rise to puss.

Bacteriophage
Phagocytosis is the process by which a white blood cell engulfs and destroys pathogens such as bacteria or viruses. In this process, the white blood cell surrounds the pathogen with its cell membrane, forming a vesicle called a phagosome, which then fuses with lysosomes to break down the pathogen.
