Cholecystitis refers to inflammation of which organ?

• A. Inflammation of the liver
• B. Inflammation of the pancreas
• C. Inflammation of the intestines
• D. Inflammation of the gallbladder

Answer: (D)

Cholecystitis is inflammation of the gallbladder. The gallbladder stores and concentrates bile produced by the liver and releases it into the small intestine. When it becomes inflamed—often because a gallstone blocks the cystic duct—the gallbladder wall swells and irritation occurs. This distinguishes it from inflammation of the liver (hepatitis), the pancreas (pancreatitis), or the intestines (enteritis), which involve those specific organs rather than the gallbladder.
