BIOL 2200 PATHOPHYSIOLOGY: CASE STUDY 1/2 REVIEW RATED A+ Explain the 3 plasma protein systems of the chemical portion of inflammation 1. Clotting proteins: Cascade reactions that activate proteins which produces fibrin net that traps pathogens and forms a clot. 2. Complement System: Cascade reactions that activate proteins which kills pathogens directly or intensify reactions of other components of the inflammatory response = very strong defenders against bacterial infection 3. ...
