Which is the shortest section of the small intestine?

Explanation:
The duodenum is the shortest section of the small intestine. It’s the first part that immediately follows the stomach and is only about 25–30 cm long in adults. Its role is mainly mixing chyme with bile and pancreatic juice and beginning digestion, while the jejunum and ileum (the next sections) extend for much longer lengths to maximize absorption, each of which runs for meters. The cecum is not part of the small intestine at all—it’s the beginning section of the large intestine. So, the duodenum is the shortest portion of the small intestine.
