Explanation:

• Question 9:
• Bile is produced by the liver. Secretin is a hormone that stimulates the liver to secrete bile. The pancreas secretes pancreatic juice (not bile). The gallbladder stores and concentrates bile (it does not secrete bile). The small intestine does not secrete bile.
• Question 10:
• The small intestine has three parts: duodenum (first part), jejunum (middle part), and ileum (last part). The colon is part of the large intestine.

Answer:

• Question 9: liver; secretin
• Question 10: duodenum
