If the human stomach ia after the small intestine, what will happen?

[templelane]

How would this happen?

[Unknown008]

Anyway, perhaps that there will be a sort of incomplete digestion of the overall food. The stomach is said to mix the food and start digestion of proteins. If the food is unproperly mix in the small intestines, my opinion is that more food will be digested than if the stomach was after the small intestines. The later breaking of the remining proteins will not even be absorbed in the rest of the alimentary canal.

(I may be wrong but this is only a suggestion)

Do body cells need nurtrients

[asking]

The cells of the body definitely need nutrients--sugars, amino acids, and fatty acids. These are passed from the chyme in the small intestine to the blood in the circulation, so they can go to all the cells.

The stomach is highly acid and starts the breakdown of proteins. It also churns the food vigorously and helps break the food into smaller chunks.

As the chyme leaves the stomach, bile from the liver and pancreatic juice from the pancreas dump into the duodenum (top of small intestine) and neutralize the stomach acid. The different enzymes from the pancreas break down protein, carbs, and fats and the si absorbs these nutrients. If the stomach came after the si, most of the digestion and absorption would already have occurred and there would be nothing left for the stomach to do.

If the food came directly from the esophagus to the small intestine, how do you think that would affect digestion?
