How phagocytes protect us from pathogens?

Phagocytes, such as macrophages and neutrophils, protect the body from pathogens by identifying and engulfing these harmful microorganisms through a process called phagocytosis. Once inside the phagocyte, pathogens are enclosed in a specialized compartment and destroyed by digestive enzymes and reactive oxygen species. Additionally, phagocytes play a crucial role in alerting the immune system by presenting antigens from the pathogens to other immune cells, thereby enhancing the overall immune response. This coordinated action helps to eliminate infections and maintain health.
