Final answer:
The digestive juices from the liver, which include bile, are delivered to the duodenum. Bile is produced in the liver, stored in the gallbladder, and helps in the digestion of fats in the duodenum. Most fat-digesting enzymes are produced in the pancreas.
Step-by-step explanation:
The digestive juices from the liver are delivered to the duodenum. Specifically, bile is produced by the liver and stored and concentrated in the gallbladder; it is then secreted into the duodenum through the bile duct. Bile contains bile salts, which emulsify lipids, thus making them accessible to water-soluble enzymes necessary for fat digestion. As for fat-digesting enzymes, most are produced by the pancreas and delivered to the duodenum where the majority of fat digestion takes place. Therefore, in regards to the questions presented, the correct answers are (b) Duodenum for the delivery of digestive juices from the liver, and (d) Pancreas for the production of most fat-digesting enzymes.
