Explanation:
Detailed explanation-1: -Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN.
Detailed explanation-2: -The innate immune system is the body’s first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “nonspecific” immune system.
Detailed explanation-3: -2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall). 3) Antibodies facilitate phagocytosis of foreign substances by phagocytic cells (opsonization).
