Inflammation is a natural response of the immune system to protect the body from harmful stimuli, such as pathogens, irritants, or damaged cells. It is characterized by a series of signs and features, including:
1. Redness (Rubor): Inflammation causes increased blood flow to the affected area, resulting in redness or discoloration.
2. Heat (Calor): The increased blood flow also leads to warmth or heat in the inflamed area.
3. Swelling (Tumor): Inflammation causes an accumulation of fluid and immune cells, leading to swelling or edema.
4. Pain (Dolor): Inflammatory mediators can stimulate nerve endings, causing pain or discomfort in the affected area.
5. Loss of function (Functio laesa): Inflammation can impair the normal function of the affected tissue or organ, leading to limitations in movement or functionality.
6. Increased blood flow: Inflammation causes the dilation of blood vessels, resulting in increased blood flow to the affected area.
7. Immune cell infiltration: Inflammatory mediators attract immune cells, such as neutrophils and macrophages, to the site of inflammation to fight off pathogens or remove damaged cells.
These signs and features of inflammation are part of the body's defense mechanism to initiate the healing process. However, chronic or excessive inflammation can lead to tissue damage and contribute to various diseases, such as arthritis, asthma, or inflammatory bowel disease.
