White blood cells combat disease through phagocytosis. This describes which function?

Phagocytosis is a defense process where white blood cells, such as neutrophils and macrophages, engulf and digest invading pathogens and debris. This is a primary way the immune system protects the body from infection, so it describes a defence function. Heat regulation relates to keeping body temperature, clotting to stopping bleeding, and transport to moving substances in the blood or lymph—none of which involve the direct engulfing and digestion of pathogens.
