Correct answer: C. Cholecystokinin
- A. Secretin
- B. Gastrin
- C. Cholecystokinin
- D. Somatostatin

About Digestive System
The digestive system covers the structure and functions of the alimentary canal from mouth to anus, along with the liver, gallbladder and pancreas. It explains mechanical and chemical digestion, the action of major enzymes, absorption through intestinal villi, and how digestion differs from absorption and assimilation.
