d) Small Intestine:
The food, remember that at this stage is already known as chyme, reaches the lower part of the gastrointestinal tract through the pyloric sphincter of the stomach. After leaving the stomach, Chyme enters the duodenum, the first segment of the small intestine located inferior to and to the right of the stomach. In addition to chyme, the duodenum also receives bile from the gallbladder and liver, as well as pancreatic juice from the pancreas. Bile and pancreatic juice mix with chyme in the duodenum to neutralize its acidity, and so, breaking chyme down into its most basic elements.
The second part occurs in the other two parts of the small intestine, jejunum and Ileum, where the nutrients are absorbed into the bloodstream. The blood then carries the useful substances around the body to where they are needed. Also, a milky fluid called chyle is produced here and then transported through the lymphatic system to the rest of the body.
