Which condition is inflammation of the lungs?

• A. Appendicitis
• B. Bradycardia
• C. Pneumonia
• D. Angiography

Answer: (C)

Inflammation of the lungs is pneumonia. Pneumonia occurs when infection inflames the lung tissue, causing the air sacs (alveoli) to fill with fluid or pus. That fluid buildup impairs gas exchange, leading to symptoms such as cough, fever, chest discomfort, and shortness of breath. On examination you may hear crackles in the lungs, and chest imaging often shows a localized area of opacity called consolidation, which helps confirm the diagnosis. This makes pneumonia the best match for “inflammation of the lungs.” Other options involve different parts or processes: inflammation of the appendix is appendicitis and presents with abdominal pain; bradycardia is a slow heart rate; angiography is an imaging test of blood vessels, not a lung condition.
