ANATOMY

Detailed explanation-1: -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-2: -What is swelling? Swelling is any abnormal enlargement of a body part. It is typically the result of inflammation or a buildup of fluid.

Detailed explanation-3: -The inflammatory response increases the amount of blood flow to the site of injury to get more nutrients and white blood cells to an area in need. To increase blood flow to the area, the blood vessels get wider (dilate).

Detailed explanation-4: -When inflammation happens, chemicals from your body’s white blood cells enter your blood or tissues to protect your body from invaders. This raises the blood flow to the area of injury or infection. It can cause redness and warmth. Some of the chemicals cause fluid to leak into your tissues, resulting in swelling.

Detailed explanation-5: -Irrespective of the characteristic of the pain, whether it is sharp, dull, aching, burning, stabbing, numbing or tingling, all pain arise from inflammation and the inflammatory response.
