"Asthma is primarily caused by bacterial infections that affect the airways."
"In asthma, the airways become narrowed due to the accumulation of excess mucus."
"Asthma results from a chronic inflammation of the airway walls and increased airway reactivity."
"The primary issue in asthma is a lack of oxygen in the bloodstream."
