Answer:
The first part of the small intestine is called duodenum
Explanation:
The small intestine is a tightly folded tube which connects to the stomach on the top end and to the large intestine on the bottom end.
The small intestine consists of three parts:
- jejunum (absorbs sugars, amino acids, and fatty acids)
- ileum (absorbs remaining nutrients that did not get absorbed by the duodenum or jejunum)
Duodenum is responsible for completing the first phase of digestion. In this section of the intestine, food is mixed with enzymes and bile which help break down food.
