Definition • “Asthma is a chronic condition of the airways of your lungs, and it has two main components – constriction, the tightening of the muscles surrounding the airways, and inflammation, the swelling, and irritation of the airways.” http://www.shef.ac.uk/janedavidson/breathing.jpeg www.lawrencehallofscience.org

  3. www2.hanover.edu library.thinkquest.org/.../scroll.htm History • Around for 2000 years! • 25 B.C.
