Final answer:
The question discusses bronchial obstruction due to constriction, a symptom of asthma, which is a chronic lung disease characterized by inflamed and narrow airways, leading to difficulty breathing during asthma attacks.
Step-by-step explanation:
The student's question pertains to episodes of bronchial obstruction due to constriction, which is characteristic of asthma. Asthma is a chronic disease involving the airways in the lungs. These airways, or bronchial tubes, allow air to come in and out of the lungs. During asthma flare-ups, known as asthma attacks, the airways become inflamed and narrowed, restricting air flow.
Bronchospasms are a key component of asthma; they are periodic contractions of the bronchial muscle that narrow the airways. This condition can be triggered by various environmental factors like dust, pollen, and respiratory infections, or by physical activities and stress. The inflammation in asthma can lead to edema (fluid accumulation) or increased mucus production, leading to further obstruction of the airways and difficulty breathing.
To manage asthma, it's crucial to take prescribed medication and avoid contact with known triggers. Acute bronchitis, on the other hand, is usually a short-term condition often following a cold or flu, and it involves inflammation and mucus build-up in the bronchial tubes without the chronic aspect of asthma.
