Respuesta :
After the digestion of carbohydrates, fats, and proteins in duodenum, the digested nutrients are absorbed in the ileum.
Ileum is a section of the small intestine, after duodenum.
Food is absorbed by diffusion and active transport. Villi on the walls of the ileum helps this process, since it can increase its surface area and provide a good blood supply, thus increase the rate of absorption.
Note that water can also be absorbed in the large intestine, those water absorbed there are the ones that cannot be absorbed in the ileum.
However, not all water is absorbed as we can notice that faeces are wet.

The absorption of nutrients that resulted from the digestion of fats and proteins occurs in the small intestine.
DIGESTION:
- Digestion is the breakdown of large molecules into smaller molecules in the body. Food is ingested and subsequently digested in the alimentary canal.
- Fats and proteins are two complex biomolecules contained in food molecules we consume. They, therefore, need to be digested into smaller molecules (nutrients).
- The nutrients are absorbed into the bloodstream in the ileum of the small intestine. A tissue called microvilli is responsible for the absorption.
- Therefore, the absorption of nutrients that resulted from the digestion of fats and proteins occurs in the small intestine.
