There are five sections within the book. The first section surveys the respiratory system and details the mechanism of breathing. It also deals with exercises related to respiration and the ill-effects of smoking. Sections 2, 3, and 4 focus on the major regions of the respiratory system, from the mouth, nose, and bronchial tubes, to the lungs and their associated blood circulation. Section 5 deals with the nonrespiratory functions of these regions, especially speech. Within each section, normal structure and function are followed by the principles of healthcare and fitness. These are followed by a survey of the main disorders and diseases affecting the region. Information is presented as double-page topics arranged in subsections.
