The liver receives the bulk of the water soluble nutrients.Little absorption occurs in the oral cavity, esophagus, and stomach. The small and large intestines are where most absorption takes place. The blood flows from the intestines back to the liver via the portal vein.
Nutrients are absorbed throughout the digestive process. Specific nutrients are absorbed in the stomach and large intestines, but the majority of nutrients are absorbed in the small intestines.
Your intestines need bacteria to break down different types of nutrients into usable chemicals for your body.
The digestive system, basically the small intestines.
The stomach is considered an organ, and it is part of the digestive system.
