Summary

In this lesson, you explored the following questions:

• How is the rate of breathing controlled?
• How does technology provide solutions to the treatment of disorders affecting the respiratory system?

A person's quality of health and environment are important in preventing respiratory disease. Lifestyle choices, such as smoking make a person much more likely to develop lung cancer or emphysema.

Breathing rate is controlled by both the concentration of oxygen and carbon dioxide in the blood.
