ANATOMY

Detailed explanation-1: -Asides from squeezing and churning the food bolus, it also secretes a mixture of compounds, collectively known as “gastric juice.” Gastric juice comprises water, mucus, hydrochloric acid, pepsin, and intrinsic factor. Of these five components, pepsin is the principal enzyme involved in protein digestion.

Detailed explanation-2: -Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin.

Detailed explanation-3: -Gastric juice is made up of 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.

Detailed explanation-4: -Final answer: Gastric juice contains pepsin, lipase and rennin.

Detailed explanation-5: -HCl (Hydrochloric Acid) keeps the stomach pH acidic. As HCl is a strong acid, it will kill most of the bacteria present in the food. The other main function is to convert pepsinogen into pepsin.
