Explanation:
Detailed explanation-1: -After chyme is produced in the stomach, it is sent to the small intestine where most of the nutrients are absorbed. Next, it moves to the large intestine where water is absorbed and chyme becomes more concentrated. Eventually, chyme is processed into feces and is expelled through the rectum and anus.
Detailed explanation-2: -The duodenum surrounds the pancreas, in the shape of a “C” and receives chyme from the stomach, pancreatic enzymes, and bile from the liver; this is the only part of the small intestines where Brunner’s glands are present on histology.
