Phagocytosis is the process in which cells of the innate immune system, such as macrophages and neutrophils, engulf and digest pathogens. This is a characteristic of innate immunity, which provides non-specific defense against a wide variety of pathogens. Clonal selection, specificity, and gene rearrangement are characteristics of the adaptive immune system, which provides specific defense against particular pathogens.
