Hint: Respiratory disorders are disorders that affect respiration. They are also called lung diseases. Respiratory disorders are divided into two types- chronic and infectious. Chronic disorders last for a long time while infectious diseases are caused due to bacteria or viruses and generally they last for a short duration.

Complete answer-
To solve the question we should know that asthma is a respiratory disorder that affects the bronchioles and bronchi of the lungs. The inflammation of the bronchioles and bronchi is caused due to the inhalation of particles (such as pollen) from the air. Other reasons may include common cold, stress, smoking, poor lifestyle etc.
In asthma, there is narrowing and swelling of the airways which results in the production of excess mucus. This leads to difficulty in breathing and shortness of breath. It also triggers coughing, wheezing and sometimes chest pain.
Asthma is a chronic disease that is non-curable. But the symptoms of asthma can be controlled by seeking doctor’s advice and following a healthy lifestyle.

Thus the answer to the above question is that asthma is characterized by the sudden contraction of the bronchial muscle and inflammation of bronchioles that results in blockage in the flow of air through the airways. It causes difficulty in breathing due to excess mucus production.

Note:
The respiratory system consists of various parts that together help in the respiratory process. The trachea brings oxygen into the bronchi which further is divided into bronchioles. The bronchioles are further divided into a number of tiny alveoli which is the main site for the exchange of gases between blood and atmospheric air.
