Answer 1

Asthma is a chronic and serious disease in which the airways of the respiratory system become obstructed, leading to difficulty breathing, chest tightness, and wheezing.

Step-by-step explanation:

Asthma is a chronic and serious disease in which the airways of the respiratory system become obstructed, leading to great difficulty expelling air from the lungs. The airway obstruction is caused by inflammation of the airways and a tightening of the muscles around them, resulting in a narrowing of the airways. Because airways become obstructed, a person with asthma will sometimes have great difficulty breathing and will experience repeated episodes of wheezing, chest tightness, shortness of breath, and coughing.
