ABSTRACT
Intestinal phase This begins when chyme (food mixed with gastric juices) enters the duodenum, causing the secretion of three main gut hormones:
➤ gastric inhibitory peptide (GIP), which inhibits further gastric secretions and motility ➤ secretin, which inhibits further gastric secretions ➤ cholecystokinin (CCK), which inhibits stomach emptying.
