What is Asthma?

Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning.

Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. About 7 million of these people are children.

Definition- what is it: Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways.

What does it does do?: Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning.

Why do we need this system to survive?: it helps to know how the airways work.

What organs are included in this system?: your lungs

Disease: Asthma has no cure. Even when you feel fine, you still have the disease and it can flare up at any time.

How does it affect your system?: When symptoms get more intense and/or more symptoms occur, you're having an asthma attack.

What are the symptoms?: When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways.

Are there any cures or treatments availible?: they have medicine for it
