is an illness that causes a temporary blockage of the small airways in the lungs. When someone is having an "asthma attack," the smooth muscles around the airways tighten, causing the airways to become inflamed, narrow, and produce excess mucus. This makes it difficult for air to pass in and out of the lungs.

is an allergic reaction in the lungs. People who have asthma have lungs that are ticklish.
