The document discusses the structure and mechanics of the human respiratory system. It examines factors like intercostal muscles, rib cage size, diaphragm shape, air volume and pressure that affect inhalation and exhalation. A model is presented to demonstrate the process of breathing over time through inhalation and exhalation.
