Which term describes inflammation of the inner lining of the heart?

• A. Ascites
• B. Hemorrhoids
• C. Erythema
• D. Endocarditis

Answer: (D)

Inflammation of the inner lining of the heart is endocarditis. The heart’s inner lining is called the endocardium, and the suffix -itis indicates inflammation, so combining endocardium with -itis gives endocarditis. This term specifically names inflammation affecting that inner heart layer, which can involve the heart valves as well.

The other terms refer to different body areas: ascites is the buildup of fluid in the abdominal cavity, hemorrhoids are swollen veins in the anal area, and erythema is redness of the skin due to inflammation.
