- Intestinal glands secrete alkaline intestinal juice (succus entericus) which contains enzymes such as maltase, lactase, sucrase, dipeptidase, lipases, nucleotidases, nucleosidases etc.The bicarbonate and mucous provide alkaline medium and protect intestinal mucosa.he gastric lipase hydrolyses a small amount of lipids. Â· Digestion in small intestine: Chyme is mixed with succus entericus, pancreatic juice & bile juice. Pancreatic juice & bile reach the duodenum through hepato-pancreatic duct.
The stomach lining is covered by a protective layer of mucus. Glands in the stomach produce mucus, hydrochloric acid and an inactive enzyme called pepsinogen. In the stomach cavity, the hydrochloric acid changes the pepsinogen into an active digestive enzyme called pepsin. This enzyme digests proteins. The mucus layer acts as a barrier which prevents the stomach lining from being attacked by pepsin and acid. If the mucus layer in the stomach is thinned or removed, which may happen during an infection by a bacterium called Helicobacter pylori, pepsin and acid may be able to attack the stomach lining. The infection can cause inflammation (gastritis) and sores called ulcers.
