Question

In which of the following diseases,alveoli are deprived of oxygen due to flattening of tracheal vessels?
A) Bronchitis
B) Asthma
C) Pneumonia
D) Emphysema

Answer 1

Hint:The trachea which is also known as the windpipe helps in the passage of air to the larynx and primary bronchi and finally to the alveoli. Alveoli are minute air sacs that are present in the lungs where the exchange of oxygen and carbon dioxide takes place.

Complete answer:
The proper functioning of the trachea and alveoli is required to maintain a proper respiratory system. Damage to any of the members of the respiratory system leads to diseased conditions. Bronchitis is a disease that is caused due to the inflammation of the bronchi in the lungs. It is mostly caused by viral infections and few symptoms include coughing, shortness of breath and wheezing. Asthma is a long term respiratory disease that is also caused by inflammation of the airways and flattening of the tracheal vessel. It is either genetic or caused due to various environmental factors and characterised by coughing, shortness of breath and wheezing. Pneumonia is an infection of lungs that affects the alveoli. It is caused by either viral or bacterial infections, where the alveoli are filled up with fluid or pus making it difficult for the affected person to breath. Emphysema is a disease where the alveoli become damaged and stretched. It is most commonly caused due to smoking and is characterised by coughing and also difficulty in breathing.

So the correct answer is option (B) Asthma.

Note:The respiratory system comprises various components, most important among them is alveoli. A proper functioning of them is required to provide the body with oxygen, which in turn takes part in many metabolic processes of the body.
