What medical condition is referred to as pleuritis?

• A. Infection of the lungs
• B. Inflammation of the pleura
• C. Obstruction of the airway
• D. Accumulation of fluid in the lungs

Answer: (B)

Pleuritis, also known as pleurisy, specifically refers to the inflammation of the pleura, which are the membranes surrounding the lungs and lining the chest cavity. When these membranes become inflamed, it can result in sharp chest pain that worsens with breathing, coughing, or moving. The condition can occur due to various causes including infections (such as viral or bacterial pneumonia), autoimmune diseases, or even certain medications.

The other options focus on distinct conditions related to the respiratory system: infection of the lungs usually indicates pneumonia or other lung infections, airway obstruction pertains to blockages that prevent normal breathing, and fluid accumulation in the lungs often describes conditions like pulmonary edema or pleural effusion. While these related issues can have overlaps in symptoms or consequences, pleuritis is specifically concerned with the inflammation of the pleura itself, making the distinction vital for accurate diagnosis and treatment.
