Question

If you have eaten a meal containing starch and sugar. Do both of these need to be digested inside your alimentary canal? Give reasoning

Answer 1

Answer:

Yes.

Explanation:

The alimentary canal comprises the mouth, pharynx, esophagus, stomach, small and large intestines, rectum and anus. Digestion of starch takes place in the mouth, partially in the stomach, and the small intestine. Starch breaks down into sugar and sugar is broken down into glucose in the small intestine which is then released into the blood stream. Therefore the digestion of both starch and sugar takes place in the alimentary canal.
