Learning Targets:
- Know the anatomical parts of the respiratory system.
- Describe gas exchange in the lungs.
- Describe why surface area is important in the lungs.
- Describe vital capacity and tidal volume
- Outline the steps of inhalation and exhalation using all of the organs involved in the process.
- Identify the causes and symptoms of common respiratory disorders.
- Conduct a spirometry exam using a spirometer to determine lung capacity and volume

The Respiratory System
The Respiratory System
The inner surface of the thoracic cavity and the outer surface of the lungs are lined with pleural membranes which adhere to each other. If air is introduced between them, the adhesion is broken and the natural elasticity of the lung causes it to collapse. This can occur from trauma. And it is sometimes induced deliberately to allow the lung to rest. In either case, reinflation occurs as the air is gradually absorbed by the tissues...
Biotopics: The Human Respiratory System
Questions, answers and diagrams on the human respiratory system.
Primary function is to obtain oxygen for use by body's cells & eliminate carbon dioxide that cells produce. Includes respiratory airways leading into (& out of) lungs plus the lungs themselves. Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Gas Exchange
Gas Exchange
This site provides an easy to understand overview of asthma, it's causes.
This site is hosted by the NIH, and provides information about asthma, including it's causes, diagnosis, and treatments.
An animated diagram by the BBC showing the basics of gas exchange.
Lesson 11 - The Respiratory System
An introduction to the respiratory system. At the end of each page is a quiz to test yourself. Good for those with no prior knowledge.
Part of the Online biology book, this chapter examines various methods of gas exchange in different organisms, the human respiratory system, diseases of the respiratory system, control of respiration, plus more.
This website provides images and details of the human respiratory system.
Uses photos and diagrams to explore the nature of tracheal breathing in insects and other invertebrates.
