An organ that processes absorbed nutrients and makes bile.

• A. Liver
• B. Pancreas
• C. Kidney
• D. Spleen

Answer: (A)

The organ that processes absorbed nutrients and makes bile is the liver. After you eat, nutrients from the digestive tract travel to the liver via the hepatic portal vein, where hepatocytes metabolize carbohydrates, proteins, and fats, store glucose as glycogen, detoxify substances, and synthesize essential proteins. The liver also produces bile, a digestive fluid that helps break down fats; bile is sent through ducts to be stored in the gallbladder until needed in the small intestine. The pancreas mainly provides digestive enzymes and bicarbonate, not bile production. The kidneys filter blood and regulate fluids, unrelated to bile, and the spleen is involved in immune function and blood cell turnover, not bile. So the liver best fits both roles described.
