Which statement regarding food entering the duodenum is incorrect?

The statement that fats are absorbed in the duodenum is not accurate. While the duodenum is indeed a critical site for the digestion and emulsification of fats due to the presence of bile and pancreatic lipases, the actual absorption of fats primarily occurs in the jejunum, which follows the duodenum in the small intestine.

At this stage, the duodenum focuses on the breakdown of food components. Carbohydrates are partially digested with the help of pancreatic amylase, proteins continue their digestion through the action of proteolytic enzymes, and digestive enzymes are actively released from the pancreas as well as bile from the liver to aid in the digestion of fats, proteins, and carbohydrates. Therefore, while fats are being processed in the duodenum, they have not yet undergone absorption at that point in the digestive system.
