Question

Which of the following is a condition in emphysema?

• A. The respiratory center is inhibited
• B. Lots of fluid in the lungs
• C. The walls separating the alveoli break
• D. Lungs have excess O₂

Answer 1

The correct option is C

The walls separating the alveoli break

The correct option is C.

Explanation of the correct option:

1. Emphysema is related to the condition in the lungs which causes shortness of breath.
2. In this condition, the alveoli i.e.,air-sacs are damaged which weakens and ruptures the walls of the alveoli and forms large air spaces.

Explanation of the incorrect option:

Option A:

Anoxia is the condition when the body/ brain loses the supply of oxygen completely and during this state respiratory centre is inhibited.

Option B:

Pulmonary edema happens when lots of fluid in the lungs gets collected in the air sacs in the lungs and makes it difficult to breathe.

Option D:

When lungs have excess O₂ i.e., oxygen toxicity happens by breathing in too much oxygen leading to oxygen poisoning. This can cause coughing and trouble in breathing.

Final answer: The walls separating the alveoli break is a condition in emphysema.
