partially digested food in the stomach is also known as
Chyme (/kaÉªm/ ; from Greek ÏÏÎ¼ÏÏ khymos, juice) is the semifluid mass of partly digested food that is expelled by the stomach into the duodenum and moves through the intestines during digestion.ith a pH of approximately 2, chyme emerging from the stomach is very acidic. The duodenum secretes a hormone, cholecystokinin (CCK), which causes the gall bladder to contract, releasing alkaline bile into the duodenum. CCK also causes the release of digestive enzymes from the pancreas.
