Hint: Gastric acid, within the stomach lining formed. It is a digestive fluid. protons and chloride are the gastric acid active components. Into the bloodstream ,the parietal cell releases bicarbonate in the process. About 1.5 liters of gastric acid daily a typical adult human stomach will secrete.

Complete answer:
(1) pepsin, lipase, and rennin in it Gastric juice has. As pepsinogen in an inert form which is activated by hydrochloric acid Pepsin is secreted. Pepsin metabolises proteins into peptones. Lipase helps to break the presence of fat in our body into fatty acids. Rennin is a proteolytic enzyme that is useful for milk coagulation.
(2) Succus entericus also Known as intestinal juice and is a fluid secreted in the small intestine in small quantities. It is produced by glands in the duodenum wall, Succus entericus is the alkaline secretion that consists of water, mucoproteins, and carbonate hydrogen ions. along with the secretions of goblet cells this intestinal juice is formed by the secretions of the mucosal brush boundary cells. entering from the stomach it helps counteract the highly acidic and proteolytic chyme into the small intestine, and thus protects the duodenum against damage.

By the intestinal gland the Succus entericus is secreted. In an inactive form, Pepsin is secreted as pepsinogen, and is activated by HCl. Such as maltase, lipases, nucleosidases, dipeptidases, etc. Intestinal juice contains a variety of enzymes.
