What is the function of digestive juices Class 10?
Digestive juices – break down protein into simpler substances. The food from stomach eventually moves into the small intestine.
What are digestive juices?
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.
What is the function of acid and digestive juices in the stomach?

How is gastric juice secreted?
Gastric secretion is stimulated by the act of eating (cephalic phase) and the arrival of food in the stomach (gastric phase).
