Chymus (ancient Greek χυμός chymós, German, juice) is the foodstuff which is produced in the stomach from the absorbed foods under the influence of digestive secretions (saliva and digestive enzymes and hydrochloric acid-rich gastric juice). This process is called chymification. The chyme is intermixed by gastric contraction, and then released into the duodenum, the first section of the small intestine, via the gastropod (pylorus). The chyme is acidic, on the average it has a pH of about 2. To increase the pH value when entering the duodenum, to alkalize the chyme, the gall bladder is contracted under the influence of the hormone cholecystokinin (CCK) with plenty of sodium bicarbonate released into the duodenum, and the chyme is largely neutralized there before reaching the jejunum, the second section of the small intestine.
