digestive enzymes, hydrochloric acid
and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins.
What does stomach fluid contain?
Gastric
juice is a variable mixture of water, hydrochloric
acid
, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric
acid
content, and it is rich in enzymes.

secreted from the highly specialized parietal cells located in the corpus of the stomach

+
concentration in the gastric juice that is 3 million times greater than that in blood and tissue. The process is controlled by a complex system of endocrine cells and neurons.
