The statement that bicarbonate is released into the duodenum during the process of digestion is true. The Brunner glands in the duodenum secrete mucus that contains sodium bicarbonate which neutralizes the acid in chyme thereby protecting the duodenum.
You have the hydrochloric acid there in the digestive tract. That means in the stomach and proximal part of the duodenum. The acid is very strong. The pH can go down to 2.
juices from liver, pancreas, and gallbladder
Hydrochloric acid is the acid produced in the stomach. It helps in the digestion of food by breaking it down and also kills harmful bacteria to prevent infections. The lining of the stomach is protected from the acid by a layer of mucus.
bicarbonate-rich fluid
The duodenum also regulates the rate of emptying of the stomach via hormonal pathways. Secretin and cholecystokinin are released from cells in the duodenal epithelium in response to acidic and fatty stimuli present there when the pylorus opens and releases gastric chyme into the duodenum for further digestion. These cause the liver and gall bladder to release bile, and the pancreas to release bicarbonate and digestive enzymes such as trypsin, lipase and amylase into the duodenum as they are needed. The bicarbonate released by the pancreas is to neutralize the hydrochloric acid coming from the stomach.
