The primary purpose of the vascular changes in an invaded or injured area is to bring to the affected area phagocytes and plasma proteins that defend against the offending agent. This process, known as inflammation, results in swelling, redness, heat, and pain. However, the primary purpose is to defend against the offending agent rather than to produce these symptoms. Pus is a result of inflammation and the accumulation of dead cells, bacteria, and fluids. While anti-inflammatory mechanisms can help to protect against damage, they are not the primary purpose of the vascular changes. Specific immune responses are triggered by the presence of antigens, which are not necessarily involved in every instance of inflammation.
