Final answer:
Phagocytes are types of white blood cells that participate in phagocytosis. Neutrophils and macrophages are the main types of phagocytes. Neutrophils are highly numerous and arrive first at the site of infection, while macrophages are larger and more efficient.
Step-by-step explanation:
Phagocytes are types of white blood cells that participate in the process of phagocytosis, which is the engulfing and destruction of pathogens. The main types of phagocytes are neutrophils and macrophages. Neutrophils are the most numerous phagocytes and are usually the first to arrive at the site of infection. They engulf and destroy pathogens by surrounding them and releasing digestive enzymes. Macrophages are larger and more efficient phagocytes that develop from monocytes. They also engulf and destroy pathogens, and they produce various chemicals and enzymes in addition to their phagocytic action.
