The digestive process continues as chyme from the stomach enters the small intestine. The main job of the small intestine is to absorb essential nutrients into the bloodstream. The small intestine is made up of three parts:
The small intestine is aided in its work by the liver, gallbladder, and pancreas. In the duodenum, bile from the gallbladder and pancreatic secretions are added to the chyme. The jejunum and ileum are responsible for the breakdown and absorption of most nutrients, including fats, starches, proteins, vitamins and minerals.
