Which of the following symptoms is incorrect regarding emphysema?
1 Surface area of gas exchange decreases
2 Loss of elasticity in the walls of alveolar sacs
3 Alveolar septa collapse
4 Regular coughing with thick greenish yellow sputum
Explanation:
Emphysema is a chronic disorder in which alveolar walls are damaged i.e. alveolar septa collapses, due to which respiratory surface is decreased. One of the major causes of this is cigarette smoking.

In asthma, muscle spasm causes constriction of small bronchioles but not trachea because
1 Trachea has pseudostratified epithelium
2 Trachea has cartilaginous rings
3 Trachea divides into primary bronchi
4 Exchange of gases does not occur in the trachea
Explanation:
The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings.

"Emphysema" is a condition in which
1 Respiratory centre inhibited
2 Lot of fluid in the lungs
3 The walls separating the alveoli break
4 Lungs have more \(\mathrm{O}_{2}\)
Explanation:
Emphysema is a type of COPD (Chronic Obstructive Pulmonary Disease) involving damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise. The most common cause is cigarette smoking

Which one of the following is the correct statement for respiration in humans?
1 Cigarette smoking may lead to inflammation of bronchi.
2 Neural signals from pneumotoxic centre in pons region of brain can increase the duration of inspiration.
3 Workers in grinding and stone breaking industries may suffer from lung fibrosis.
4 About \(90 \%\) of carbon dioxide \(\left(\mathrm{CO}_{2}\right)\) carried by haemoglobin.
Explanation:
Irritating gases, fumes, dust etc., present in the work place result in lung disorders. This is because the defence mechanism of the body cannot fully cope with this situation of so much dust. Long exposure can give to fibrous tissue) and thus causing serious lung damage.

Which of the following is not a lung disorder?
1 Asthma
2 Emphysema
3 Silicosis
