Detailed explanation-1: -Inflammation is one of the first responses of the immune system to infection or irritation. Inflammation is stimulated by chemical factors released by injured cells. It establishes a physical barrier against the spread of infection and promotes healing of any damaged tissue following pathogen clearance.
Detailed explanation-2: -The innate immune system includes physical and anatomical barriers as well as effector cells, antimicrobial peptides, soluble mediators, and cell receptors (Table 1). Skin and mucosa provide an effective immune barrier between the internal and external environment.
Detailed explanation-3: -After trauma, various pathways of innate immunity can induce posttraumatic endotheliopathy and further tissue damage.
