Which part of the respiratory system contains the vocal cords responsible for sound production?
Larynx
How do the vocal cords in the larynx contribute to breathing and communication?
They vibrate to produce sound while allowing air to pass through for breathing.
What disease causes long-term damage to alveoli, leading to difficulty in exhaling air from the lungs?
Emphysema
A person loses their voice after shouting at a concert and feels throat discomfort. What part of the respiratory system might be affected, and what can they do?
Larynx irritation; rest the voice, stay hydrated, and avoid strain.
What dome-shaped muscle separates the chest cavity from the abdomen and assists in respiration?
Diaphragm
What is the role of the pleura in ensuring smooth lung movement during breathing?
The pleura reduces friction between the lungs and chest wall, allowing smooth expansion and contraction.
Which bacterial infection causes small nodules to form in lung tissue and spreads via airborne droplets?
Tuberculosis (TB)
A factory worker experiences frequent coughing and chest tightness after exposure to dust. What could be happening, and what should they do?
Occupational asthma; seek medical evaluation, wear protective gear, and reduce exposure.
1200: What thin, double-layered membrane covers the lungs and lines the chest cavity to reduce friction?
Pleura
How do the cilia help maintain a clean and healthy respiratory tract?
Cilia moves mucus and trapped particles up toward the throat, preventing infections.
What chronic condition involves inflammation of the bronchial tubes, often triggered by allergens or irritants?
Chronic bronchitis
Someone with chronic bronchitis has worsening symptoms during winter. What might be the reason, and what treatments should they consider?
Cold air exacerbation; consider bronchodilators, humidifiers, and wearing a mask.
What are the tiny hair-like structures in the respiratory tract that move mucus and trapped particles out of the airways?
Cilia
Why is the diaphragm essential for regulating air pressure in the lungs during breathing?
The diaphragm controls lung expansion and contraction by changing thoracic pressure during inhalation and exhalation.
What lung condition involves scarring of lung tissue, leading to stiffness and reduced oxygen intake?
Pulmonary fibrosis
After years of working in a mine, a person develops breathing difficulties and fatigue. What respiratory condition could this be, and how should it be managed?
Pneumoconiosis (black lung disease); consult a specialist, use oxygen therapy, and limit further exposur
