Introduction
The word asthma originates from an ancient Greek word meaning panting. Essentially, asthma is an inability to breathe properly. When any person inhales, the air travels through the following structures:
- Air passes into the lungs and flows through progressively smaller airways called bronchioles. The lungs contain millions of these airways.
- All bronchioles lead to alveoli, which are microscopic sacs where oxygen and carbon dioxide are exchanged.
