Explanation:
Detailed explanation-1: -The adaptive immune response in B cells, Helper T cells and Cytotoxic T cells involved four phases: encounter, activation, attack, and memory.
Detailed explanation-2: -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-3: -Neutrophils are considered the first responders of the innate immune system. Neutrophils and macrophages circulate though the blood and reside in tissues watching for potential problems. Both cells can “eat” bacteria, as well as communicate with other immune cells if an issue arises.
