Question

the common bile duct empties into the: a stomach. b liver. c gallbladder. d duodenum.

Explanation:

The common bile duct is part of the biliary system. The liver produces bile, which is stored in the gallbladder. When food (especially fatty food) enters the duodenum (the first part of the small intestine), the gallbladder contracts and releases bile. The common bile duct then transports this bile (from the gallbladder and also bile from the liver itself) and empties it into the duodenum. The stomach is involved in initial digestion (e.g., with gastric acid and pepsin for protein digestion), the liver produces bile, and the gallbladder stores bile.

Answer:

D. duodenum
