Detailed explanation-1: -The normal immune response can be broken down into four main components: pathogen recognition by cells of the innate immune system, with cytokine release, complement activation and phagocytosis of antigens.
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.
