Inflammation is a 'cell mediated response' which occurs when the body's first line of defence at the site of a wound has failed to deal with an invading organism. The walls of local blood vessels enlarge & become leaky (which is why it becomes red & swollen); the extra blood flooding into the area has several purposes: # It helps to remove infectious agents from the site # Plasma dilutes the pathogen, making them easier to deal with # The extra white blood cells arriving at the site help to fight the infection
