chemicals in gastric juice are

1. Pepsin- it acts on proteins and convert them into proteoses,peptones and polypeptides.

2. Gastric lipase- it converts triglycerides into fatty acids and glycerol.

3. Gastric amylase- convert starch into dextrin and maltose.

4. Gelatinase- convert gelatin and collagen of meat into peptides.

5. Urase- convert urea into ammonia.

6. Hydrochloride acid- it activates pepsin . It also kills bacteria of stomach.

The two sphincters of stomach are-

1. Cardiac sphincter- cardiac region is upper part of stomach. The opening between oesophagus and cardiac part of stomach is guarded by cardiac sphincter.

2. Pyloric sphincter- pyloric canal opens into first part of intestine called duodenum. The opening of pyloric canal is guarded by pyloric sphincter . It opens towards duodenum.
