Detailed explanation-1: -These include neutrophils (PMNs), eosinophils, and basophils. Neutrophils are the leukocytes found in the largest numbers in the bloodstream and they primarily fight bacterial infections. Eosinophils target parasitic infections. Eosinophils and basophils are involved in allergic reactions.
Detailed explanation-2: -The body’s second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries.
Detailed explanation-3: -For example, it can trigger an increase in core body temperature to produce a fever. This can help fight a range of different pathogens by making it too hot for them to survive. Such general responses to infection make up the second line of defence.
Detailed explanation-4: -Inflammation, fever, phagocytosis, interferon, and complement are all part of the second line defenses.
