The inflammatory response is the body's natural reaction to injury or infection. When tissues are damaged, the immune system releases chemicals that increase blood flow to the affected area. This process brings white blood cells and nutrients to help fight off pathogens and begin healing. During inflammation, symptoms such as redness, heat, swelling, and pain may occur. These signs indicate that the body is working to protect itself. While inflammation is essential for healing, chronic inflammation can lead to various health issues, including heart disease and arthritis. Understanding this response is crucial for maintaining overall health.
