It results from the mechanical and chemical breakdown of a Bolus digestion bolus and consists of partially digested food, water, hydrochloric acid , and various digestive enzyme s. Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrient s begins. Depending on the quantity and contents of the meal, the stomach will digest the food into chyme anywhere between 40 minutes to a few hours. With a pH of around 2, chyme emerging from the stomach is very acidic. To raise its pH, the duodenum secretes a hormone , cholecystokinin CCK , which causes the gall bladder to contract, releasing alkaline bile into the duodenum. The duodenum also produces the hormone secretin to stimulate the pancreatic secretion of large amounts of sodium bicarbonate , which raises the chyme s pH to 7 before it reaches the jejunum . As it is protected by a thick layer of mucus and utilizes the neutralizing actions of the sodium bicarbonate and bile, the duodenum is not as sensitive to highly acidic chyme as the rest of the small intestine. At a pH of 7, the enzymes that were present from the stomach are no longer active. This then leads into the further breakdown of the nutrients still present by anaerobic bacteria which at the same time help to p ... more details
