1. RESPIRATORY SYSTEM CHAPTER 16 Objectives: 11.0 Identify structures and functions of the respiratory system. 11.1 Tracing the pathway of the oxygen and carbon dioxide exchange 11.2 Recognizing common disorders of the respiratory system

2. Introduction What are the two main functions of the respiratory system? Other functions of respiratory organs include: –Trapping particles in incoming air –Controlling temperature and moisture of incoming air –Producing vocal sounds –Aiding in sense of smell –Regulation of blood pH

3. Introduction, continued…..
