Detailed explanation-1: -What are the signs of inflammation? The four cardinal signs of inflammation are redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor). Redness is caused by the dilation of small blood vessels in the area of injury.
Detailed explanation-2: -Redness and heat are due to increased blood flow to the inflamed area; swelling is due to accumulation of fluid; pain is due to release of chemicals that stimulate nerve endings; and loss of function is due to a combination of factors.
Detailed explanation-3: -Infection involves tissue invasion by microorganisms. An inflammatory reaction will be provoked when infection occurs in an otherwise healthy patient. Inflammation can be recognized clinically by 5 cardinal signs: rubor (redness), calor (warmth), tumor (swelling), dolor (pain), and functio laesa (loss of function).
