Inflammation meaning

Inflammation is a biological response triggered by the body's immune system when it detects harmful stimuli such as pathogens, damaged cells, or irritants. It serves as a protective mechanism aimed at removing these harmful stimuli and initiating the healing process. The signs of inflammation include redness, heat, swelling, pain, and loss of function at the affected site. This response involves the release of various substances like histamines and cytokines that increase blood flow to the area, attract white blood cells to fight off invaders, and facilitate the repair of damaged tissue. While acute inflammation is essential for healing, chronic inflammation can lead to various diseases, including arthritis, heart disease, and certain cancers.
