Detailed explanation-1: -T cells and B cells are the cells of the adaptive immune system.
Detailed explanation-2: -Innate immunity can be viewed as comprising four types of defensive barriers: anatomic (skin and mucous membrane), physiologic (temperature, low pH and chemical mediators), endocytic and phagocytic, and inflammatory.
Detailed explanation-3: -Plasma cells are differentiated B-lymphocytes. They release antibodies into the bloodstream that are specific for a given pathogen. As a result, plasma cells are only present following a specific infection. They are a crucial part of the adaptive immune response, but are not involved in innate immunity.
Detailed explanation-4: -The innate immune system includes physical and anatomical barriers as well as effector cells, antimicrobial peptides, soluble mediators, and cell receptors (Table 1).
