The correctly sequenced sections of the small intestine are: , , .

The correct answer is: duodenum, jejunum, ileum.

Explanation:

The small intestine is the part of the digestive tube that is mostly responsible for the absorption of nutrients that we incorporate through our diet, although part of the digestion also occurs in this segment (specifically in the duodenum).

The first segment, the duodenum, is the shortest of the three (about 25 centimeters in length) and is the one that is connected to the stomach. The duodenum receives the bile (from the liver), the pancreatic juice (from the pancreas), and the gastric chyme (from the stomach), to digest proteins and fat.

The second segment, called the jejunum, is about 2,5 meters long and its main task is to absorb the products of digestion, such as amino acids, carbohydrates, and fatty acids. This is how the nutrients reach our bloodstream and then the tissues where they are needed.

The last segment, the ileum, is the longest (about 3 meters long) and it's responsible for the absorption of vitamin B12 and bile acids. The ileum then connects to the large intestine, where water will be absorbed.
