Which term describes the liver's functions, including making proteins, fighting infections, filtering blood, aiding digestion, and storing energy?

• A. Liver function
• B. Gallstones
• C. Heartburn/ acid reflux
• D. Diarrhea

Answer: (A)

All the activities listed—producing proteins, supporting immune defense, filtering blood, aiding digestion with bile, and storing energy—are roles of the liver. The word that describes all of these activities together is liver function. In medical context, we talk about liver function to refer to what the liver does and to assess it with tests that measure substances the liver handles, like enzymes and proteins. The other options point to problems or symptoms (gallstones, heartburn/acid reflux, diarrhea) rather than the liver’s duties, so they don’t describe what the liver does.
