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.

A chemical change is a change in which the composition of the matter is changed at the molecular level, most chemical changes are not easily irreversible, for example, an egg being cooked, the egg changes from its liquid like state to a solid, and it is not possible to revert it back to its original change. The egg itself is changed in this case.
A physical change on the other hand however, is only changing the substance of a matter, not its composition, this is usually easily reversible. For example, water turning into ice, the water's substance changed from its liquid state to its solid state, it is still water, and it can easily be turned back into water by heating it.
Sorry for the long explanation,
Hope this helps!
