i'm pretty suure.. it's digestion.
Ingestion takes place in the mouth.
Maximum digestion takes place in duodenum .
In the duodenum
The duodenum is where a lot of the food breakdown in the small intestines happens. It is the first place the food goes after it leaves the stomach, and it is where it is mixed with the enzymes from the gallbladder and pancreas.

The duodenum is the first part of the intestine; it is the place that the stomach empties it's contents into. Along with that, the duodenum is an essential digestion site. The pancreas, liver and gallbladder all secrete important digestive enzymes into the duodenum. The enzymes digest fats, proteins and fats. Much activity goes on in the duodenum, which is why the duodenum is so crucial for digestion.
The duodenum
The duodenum is in the digestive tract, and it forms the upper part of the small intestine. It connects the stomach to the jejunum, the middle part of the small intestine. A link can be found below.
Ingestion meaning the physical/initial intake of food, this is often referred to the teeth as they are the first/primary place where food ingestion occurs and later futhers this into digestion e.g) the stomach and enzymic brake down of foods.
The small intestine has three main divisions: - duodenum - jejunum, - ileum. Those are the main sections, but the duodenum could be divided further into: superior, descending, horizontal, and ascending portions.
Possibly, although there would be significant medical challenges for the rest of the person's life. The duodenum is where a lot of initial digestion takes place, and is where the exocrine pancreas and the liver secrete digestive enzymes into the digestive tract.
The section of the small intestine where nutrients are absorbed are the jejunum and the ileum. Once the digestive process takes place in the small intestine, food particles go to the large intestine.
