This results in the increased osmolarity of the surrounding tissue which shows inflammed. This condition is painful too, and red in vision.
In the internal organs, the inflammation is mediated by macrophages which secrete different factors in response to external contaminants. These tissues get wrecked by macrophages in response to antigen and is totally different from this type of inflammation.
