Phagocytes are a type of white blood cell that play a crucial role in our immune system. Their main job is to identify and engulf harmful invaders, such as bacteria and viruses. When they detect these pathogens, phagocytes surround and consume them, effectively removing the threat from the body. This process is essential for keeping us healthy and preventing infections. There are different types of phagocytes, including macrophages and neutrophils. Macrophages are larger and can consume many pathogens, while neutrophils are faster and respond quickly to infections. Together, these cells work tirelessly to protect our bodies from disease and maintain our overall health.
