Detailed explanation-1: -Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN.
Detailed explanation-2: -Chemical defenses. Among the nonspecific chemical defenses of the body are the secretions of lubricating glands. The tears and saliva contain the enzyme lysozyme, which breaks down the peptidoglycan of the cell wall of Gram-positive bacteria.
Detailed explanation-3: -Interferons and Natural Killer Cells – Defense Against Viruses: Two components of the immune system fight only viruses, interferons and natural killer cells. Since these components attack many types of viruses, they are considered as non-specific defenses.
Detailed explanation-4: -NON SPECIFIC DEFENSES: Skin and Mucous membranes, antimicrobial chemicals, natural killer cells, phagocytosis, inflammation and fever.
