Which of the following is NOT a function of the digestive system?
a) chemical and enzymatic breakdown of large organic nutrient molecules.
b) the movement of nutrient molecules into the lumen of the small intestine.
c) ingestion of foods and liquids.
d) mechanical processing of food materials and liquids.

The Organs of the Digestive System:
The digestive system is a complex system that consists of many organs that have specific functions but work together for the digestion and absorption of food. The organs of the digestive system include the major organs and the accessory organs. The major organs are salivary glands, esophagus, pharynx, stomach, small intestine, large intestine, rectum, and anus. The accessory digestive organs include the liver, gallbladder, and pancreas.
Answer and Explanation:
The correct answer is e) All of the above are functions of the digestive system..
The digestive system is a system consisting of the digestive tract and its accessory organs, which are involved in the breakdown of complex food molecules into simpler substances that can be absorbed and assimilated into the body. The digestive tract or alimentary canal is a continuous tube with two openings: the mouth and the anus. Therefore, the chemical and enzymatic breakdown of large organic nutrient molecules into smaller molecules, the movement of nutrient molecules into the lumen of the small intestine, ingestion of foods and liquids, and mechanical processing of food materials and liquids are all functions of the digestive system.
