What is the medical term for inflammation of body tissue characterized by fever, swelling, and redness?

The medical term for inflammation of body tissue characterized by fever, swelling, and redness is cellulitis. This condition occurs when bacteria enter the skin through a cut or other opening, leading to a localized infection that can produce symptoms such as warmth, swelling, and tenderness in the affected area. The body's immune response to the infection can cause fever and elevate the local inflammatory response, resulting in redness and swelling as blood flow to the area increases to combat the infection.

Understanding cellulitis is crucial in the context of skin anatomy and physiology, as it highlights not only the structure of the skin but also the skin's role as a barrier to infection and its response to injury. The condition primarily affects the dermis and subcutaneous tissue, illustrating the interaction between skin components and the immune system.
