Answer:c. duodenum of the small intestine
Explanation:
The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food.
Two solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (for instance, nerves and blood) play a major role in the digestive system.
Answer: Colon
Explanation: Food passes from stomach and small intestine to large intestine, colon, from where the absorption occurs. The food that remains undigested is removed from the colon to the rectum and then leaves through the anus.
Colon is actually a tube like long structure.
