Objectives of Part B Internal Innate Defenses: Cells and Chemicals Describe the inflammatory process. Identify several inflammatory chemicals and indicate their specific roles. Name the body’s antimicrobial substances and describe their function. Explain how fever helps protect the body. Inflammatory Response Triggered whenever body tissues injured Prevents spread of damaging agents Disposes of cell debris and pathogens Alerts adaptive immune system Sets the stage for repair © 2013 Pearson Education, Inc. Inflammatory Response Cardinal signs of acute inflammation: 1. Redness 2. Heat 3. Swelling 4. Pain (symptom) (Sometimes 5. Impairment of function) © 2013 Pearson Education, Inc. Inflammatory chemical release Begins with chemicals released into ECF by injured tissues, immune cells, blood proteins Inflammatory mediators – Kinins, prostaglandins (PGs), and complement Dilate local arterioles (hyperemia) – Causes redness and heat of inflamed region Make capillaries leaky Many attract leukocytes to area Some have inflammatory roles For further components of the Inflammatory response, read and view the following : Marieb, E.N. & Hoehn, K.
