Chapter 23 THE RESPIRATORY SYSTEM Chapter Synopsis This chapter undertakes a detailed analysis of the structure and physiology of the organs of respiration. After the anatomy and histology of the system are described, physiological aspects are discussed. These include mechanisms involved in pulmonary ventilation, compliance, airway resistance, breathing patterns and modified respiratory movements, pulmonary air volumes and capacities, exchange of respiratory gases, gas laws, gaseous exchange during external (pulmonary) and internal (tissue) respiration, the transport of oxygen and carbon dioxide, and the factors that control respiration. There is a section on the system’s developmental anatomy, and the effects of aging on the respiratory system are described. The chapter includes Focus on Homeostasis: The Respiratory System. Among the disorders considered are asthma, chronic obstructive pulmonary disease, lung cancer, pneumonia, tuberculosis, coryza and influenza, pulmonary edema, cystic fibrosis, asbestos related diseases, sudden infant death syndrome, and severe acute respiratory syndrome. Clinical applications found in this chapter include rhinoplasty, nasal polyps, laryngitis and cancer of the larynx, tracheostomy and intubation, pneumothorax and hemothorax, hyperbaric oxygenation, hypoxia, and why smokers have lowered respiratory efficiency. The chapter concludes with a glossary of medical terminology associate with the respiratory system.
