Understanding Inflammatory Etiology in Diseases

Microscopic view of human immune cells, including macrophages and neutrophils, engaging with pathogens in a vivid illustration of the inflammation process. Cellular structures are intricately detailed, highlighting the body's natural defense mechanisms.

It is a complex biological response involving immune cells, blood vessels, and molecular mediators. The purpose of inflammation is to eliminate the initial cause of cell injury, clear out necrotic cells and tissues, and establish a repair process.
