The small intestine, or the duodenum, is where most absorption of nutrients occur.
small intestine
The oragan in which the most absorbtion of nutrients occurs is the small intestine.
Eighty percent of nutrient absorption occurs in the small intestine. The other 20% occurs in the stomach tissues.
Most absorption of nutrients occurs in the small intestine. And as far as digestion itself, it would be after the food particles are small enough to diffuse through the blood capillaries.
Most of digestion occurs in the stomach and most absorption occurs in the small intestine.

Small intestine
Most food absorption takes place in the small intestine. Of the three sections of the small intestine, the duodenum and jejunum absorb the most nutrients. Some nutrients are absorbed in the stomach, but nutrients are absorbed mainly in the small intestine, where the small, soluble molecules are diffused or actively transported from the ileum/duodenum, into the capillaries on the other side of the intestine.
