Asthma is very common, but it isnt well understood. Current treatments for the disease are getting to be more effective. In the future, hopefully advances in medical research will lead to even better treatments then the ones we currently have. We use our lungs to breathe they work by taking oxygen from the air we breathe in and then disposing it as carbon dioxide; Carbon Dioxide is a deadly waste product made by the cells of the body. Once this exchange has taken place, Carbon dioxide is removed from the body by breathing it out, or exhaling.Asthma is a disorder that interferes with the lungs and the airways to the lungs. It causes attacks of wheezing and difficult breathing. An asthma attack occurs when the airways respond to some kind of trigger, Some examples of triggers for Asthma attacks are dust, mold, pets, exercise, cold weather, and some attacks start for no known reason. The triggers may irritate the airways to the lungs, allowing disease-fighting cells to build up and causing the lungs to swell up. In addition, the airways could get blocked when the muscles surrounding the lungs tighten. This keeps air from circulating freely in the lungs. Or, mucus may clog and narrow the airways in the lungs, making breathing even more difficult.During an asthma attack, the walls of the airways become irate, and the mucous membrane found on the walls of the lungs become swollen with fluid and mucus fills taking up the remaining space, making it difficult to breathe. *Because air cannot flow in and out of the lungs freely, a whistling or wheezing sound may be heard. During a severe attack, wheezing might stop because of the air moving in and out of the lungs are too weak to make any noise. Asthma attacks are known as three different levels they are mild, moderate, or severe, and they can last up too ass little as a few minutes, or as long as several days. Asthmas attacks can happen at any time and the can happen anywhere. Many attacks occu...
