Once the chyme begins to enter the duodenum, it must first be Neutralized before any of the enzymes in the pancreatic juices can be activated.
<u>Explanation:</u>
Chyme or chymus is the semi-liquid mass of halfway processed sustenance that is excreted by the stomach, through the pyloric valve, into the duodenum. Chyme results from the mechanical and compound breakdown of a bolus and comprise of incompletely processed sustenance, water, hydrochloric acid, and different stomach related catalysts.
Chyme gradually goes through the pyloric sphincter and into the duodenum, where the extraction of supplements starts. With a pH of roughly 2, chyme rising up out of the stomach is exceptionally acidic. The duodenum secretes a hormone, cholecystokinin (CCK), which makes the nerve bladder contract, discharging antacid bile into the duodenum.
The duodenum is a short segment of the small digestive tract situated between the stomach and the small digestive system. The duodenum additionally creates the hormone secretion to invigorate the pancreatic emission of a lot of sodium bicarbonate, which at that point raises pH of the chyme to 7 and this process is called as neutalization of chyme.
