Answer:
The duodenum is the first and shortest segment of the small intestine. It receives partially digested food (known as chyme) from the stomach and plays a vital role in the chemical digestion of chyme in preparation for absorption in the small intestine.
From its approximate length, this first part of the small intestine was called by the Greeks dodeka daktulon, meaning 12 fingers. It was translated into Arabic and ultimately emerged in Latin as duodenum in reference to its length. Jejunum - from the Latin adjective jejunus = empty or fasting.The duodenum is the first part of the small intestine.
The main role of the duodenum is to complete the first phase of digestion. In this section of the intestine, food from the stomach is mixed with enzymes from the pancreas and bile from the gallbladder. The enzymes and bile help break down food.
