Question

In which parts of the gut does chemical digestion takes place?

​

Answer 1

Answer:

The small intestine is about 20 feet (6 meters) long and has three parts: the duodenum, jejunum, and ileum. The duodenum is where most chemical digestion takes place. Here, bile from the gallbladder and enzymes from the pancreas and intestinal walls combine with the chyme to begin the final part of digestion.
