inflammationDefensive reaction of the body tissues to disease or damage, including redness, swelling, and heat. Denoted by the suffix -itis (as in appendicitis), it may be acute or chronic, and may be accompanied by the formation of pus. This is an essential part of the healing process. Inflammation occurs when damaged cells release a substance (histamine) that causes blood vessels to widen and leak into the surrounding tissues. This phenomenon accounts for the redness, swelling, and heat. Pain is due partly to the pressure of swelling and also to irritation of nerve endings. Defensive white blood cells congregate within an area of inflammation to engulf and remove foreign matter and dead tissue. |
