Overview
Gastrointestinal physiology is a branch of human physiology addressing the physical function of the gastrointestinal system.

| enteroglucagon | stomach, small intestine | - |
| gastric inhibitory peptide | duodenum, jejunum | - |
| gastrin | stomach | increases production of HCl |
| motilin | small intestine | stimulates peristalsis |
| secretin | duodenum | - |
| vasoactive intestinal peptide | stomach, large intestine, small intestine | stimulates peristalsis |
