Colitis refers to inflammation of which organ?

• A. Liver
• B. Small intestine
• C. Large intestine
• D. Stomach

Answer: (C)

Colitis is inflammation of the colon, which is part of the large intestine. The word parts show this clearly: “col-” refers to the colon, and “-itis” means inflammation. So colitis specifically targets the large intestine.

The liver would be inflamed in hepatitis, the stomach in gastritis, and the small intestine in enteritis. Knowing the root helps you connect the term to the correct organ, and it’s also why conditions like ulcerative colitis are described as inflammatory diseases of the colon.
