Phagocytosis is the process by which certain cells, such as macrophages and neutrophils, engulf and destroy microorganisms and cellular debris. Inflammation is also a nonspecific immunity mechanism, but it involves a complex series of events that result in redness, swelling, heat, and pain at the site of infection or injury. Intact skin and mucous membranes protect the body from external pathogens, while normal flora refers to the harmless bacteria that naturally reside in and on the body and help prevent pathogenic infections.
