Final answer:
e) Asthma is a chronic disease where the airways become obstructed, causing difficulty breathing. Symptoms include paroxysmal dyspnea, wheezing, and coughing. Asthma can be triggered by environmental factors.
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.
This can cause symptoms such as paroxysmal dyspnea, wheezing, and coughing. Asthma attacks can be triggered by environmental factors such as allergens, exercise, stress, or other factors.
