PATHOLOGY

Detailed explanation-1: -Your immune system sends out its first responders: inflammatory cells and cytokines (substances that stimulate more inflammatory cells). These cells begin an inflammatory response to trap bacteria and other offending agents or start healing injured tissue. The result can be pain, swelling, bruising or redness.

Detailed explanation-2: -Fever is a common symptom of infectious and inflammatory disease.

Detailed explanation-3: -The swelling process, also known as edema, is the result of acute inflammation, a response triggered by damage to living tissues. In the case of injury, the purpose of the inflammatory response is to remove components of damaged tissue in order to allow the body to begin to heal.

Detailed explanation-4: -Steps in an Inflammatory Response Blood starts to rush towards the injured region because the blood vessels dilate because of these chemicals. The breakdown of cells because of the tissue damage results in the accumulation of the cellular fluid into the surrounding tissues, which causes the injured area to swell.
