Question

Quizplus · Accepted Answer

The classic signs of inflammation,a secondary defense against infection,are erythema (redness)and localized heat.The secondary defenses of phagocytosis (process by which white blood cells engulf and destroy pathogens)and the complement cascade (process by which blood proteins trigger the release of chemicals that attack the cell membranes of pathogens)do not produce visible findings.Immunity is a tertiary defense that protects the body from future infection.
