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. Its main function is to inactivate swallowed microorganisms, thereby inhibiting infectious agents from reaching the intestine.

Detailed explanation-3: -Gastric juice has mucus, pepsin, lipase and rennin. Mucus helps in the protection of the mucosal epithelium. Pepsin converts proteins into peptides. Fats are broken down by lipases of gastric juice.

Detailed explanation-4: -Gastric juice is made up of water, electrolytes, hydrochloric acid, enzymes, mucus, and intrinsic factor. Hydrochloric acid is a strong acid secreted by the parietal cells, and it lowers your stomach’s pH to around 2.

Detailed explanation-5: -The wall of the stomach has gastric glands that secrete gastric juice. This gastric juice contains-mucus, hydrochloric acid, and protease or protein-digesting enzyme, pepsin. Role of Hydrochloric Acid: It makes the medium of gastric juice acidic so that the enzyme pepsin can digest the food properly.
