Where does nutrient digestion and then absorption take place for different nutrients along the alimentary tract?

  • $\begingroup$ Hi Carlos - Welcome to BiologySE... you're question is a bit vague... especially with the use of the term "food groups" - where have you looked for the answer to this question already? $\endgroup$ – Vance L Albaugh Nov 23 '16 at 18:27

The saliva from your mouth will slowly start to digest starches.

Then the stomach specializes in digesting protein with enzymes and its highly acidic content.

The small intestine will digest proteins, starchs and carbs (with the help of the enzymes traveling from the stomach).

The liver and pancreas secretions will join in the small intestine will help break down fats and complete digestion.

The small intestin is responsible of absorbing the vast majority of digested nutrients and the water is then mostly absorbed by the colon.
