Asthma is a condition that affects the lungs. It is characterized by difficulty in breathing, wheezing, uncontrolled coughing, a tightening of the chest, and increased mucus production. It is a condition that can strike at any age at any time. An episode of asthma can vary in severity and last for a few minutes to a few weeks. There is no known cure for asthma. Unfortunately, asthma has a wide range of triggers. One of the triggers that asthmatics struggle with is exercise (American 43). This trigger is unfortunate for asthmatics since everyone should include some sort of physical activity in life to maintain optimum health. Many people afflicted with asthma believe that a life with exercise is impossible. Exercise can bring on painful symptoms for asthmatics that can lead to a severe asthma attack. A severe asthma attack can lead to a trip to the emergency room, the use of an oxygen mask, the use of prescribed medications, and, in severe cases, death (weinstein 54).!

             There are a few babies who are born with asthma, and asthma can also develop at any time in life. Asthma is most likely to develop in childhood. Asthma in children tends to become more severe around eight to fourteen years of age. In addition, males are more likely to develop asthma than females, for reasons not yet understood (Brown 23). Most infants develop asthma due to a virus infection. Children in their teenage years owe their asthma to house dust and pets (Brown 20). Adults who acquire asthma do so because of exposure to pollens and molds. If the adult is over forty-five, chemical based irritants, infections, and cold air are the primary causes of asthma (Brown 23).
             To best understand how lungs with asthma function, a person needs information on the lungs of a healthy person. There are two organs which are part of the respiratory syst...
