Answers & Comments
(small intestine)
The food is digested in the small intestine. It is dissolved by the juices from the pancreas, liver, and intestine. The contents of the intestine are mixed and pushed forward to allow further digestion. Last, the digested nutrients are absorbed through the intestinal walls.
