Question
Chapter 52, Problem 3TY
Summary Introduction
Introduction: Any infection or injury generates a natural response in the body. This type of response is termed as inflammation. The role of inflammation is to protect the infected area from further invasion of pathogens. It also helps in tissue repair mechanism. The imitation and control of inflammation are controlled by certain chemicals.
