Final answer:
The duodenum is the first part of the small intestine where digestion takes place. If the duodenum does not go through the complete recanalization process, it can lead to a condition called duodenal atresia, causing digestion and absorption problems.
Step-by-step explanation:
In the human digestive system, the duodenum is the first part of the small intestine where food digestion takes place. The duodenum receives partially digested chyme from the stomach, along with pancreatic juices and bile. It is responsible for the mixing of chyme with digestive enzymes and the absorption of nutrients.
If the duodenum does not go through the complete recanalization process, it can lead to a condition called duodenal atresia. This condition occurs when there is a blockage or absence of a portion of the duodenum, resulting in digestion and absorption problems.
