Detailed explanation-1: -such as inflammation, complement, and non-specific cellular responses. The inflammatory response actively brings immune cells to the site of an infection by increasing blood flow to the area. Complement is an immune response that marks pathogens for destruction and makes holes in the cell membrane of the pathogen.
Detailed explanation-2: -They cause the small blood vessels in the tissue to become wider (dilate), allowing more blood to reach the injured tissue. For this reason, inflamed areas turn red and feel hot. The increased blood flow also allows more immune system cells to be carried to the injured tissue, where they help with the healing process.
Detailed explanation-3: -Usually, inflammation enables our bodies to fight off bacteria, viruses and other toxins. But if that immune response continues unchecked, even after the threat has passed, the immune system can turn on healthy tissue.
