A finding of a localized protective response resulting from injury or destruction of tissues. Inflammation serves to destroy, dilute, or wall off both the injurious agent and the injured tissue. In the acute phase, inflammation is characterized by the signs of pain, heat, redness, swelling, and loss of function. Histologically, inflammation involves a complex series of events, including dilatation of arterioles, capillaries, and venules, with increased permeability and blood flow; exudation of fluids, including plasma proteins; and leukocyte migration into the site of inflammation.

A localized physical condition in which part of the body becomes reddened, swollen, or hot and often painful.

A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

A response to an injury or abnormal stimuli characterized by inflammatory cell infiltration and varying degrees of vascular and tissue reactions (hyperemia, edema, fibrin, and/or fibrosis).

Pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions; usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

Redness, swelling, pain, and/or a feeling of heat in an area of the body. This is a protective reaction to injury, disease, or irritation of the tissues.

The body's reaction to injury or infection. It is characterized by swelling, heat, redness, and pain.

Inflammation, a response triggered by damage to living tissues. The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury. Its purpose is to localize and eliminate the injurious agent and to remove damaged tissue components so that...
