3. Inflammation
Inflammation (Latin, īnflammō, “to ignite, set alight”) is part of the complex biological response of vascular tissues (those with widespread blood vessles) to harmful stimuli, such as pathogens, damaged cells, or irritants. Inflammation is a protective attempt by the organism to remove the injurious stimuli and to initiate the healing process.
Without inflammation, wounds and infections would never heal.. However, chronic inflammation can also lead to a host of diseases, such as hay fever, periodontitis, atherosclerosis, arthritis, and even cancer. It is for that reason that inflammation is normally closely regulated by the body.
