Answer:
Gastric glands which are present in the stomach secret gastric juice.
Explanation:
The composition of gastric juice is :
Water = 99.5%
HCl = 0.2 - 0.3%
pH = 1.5 to 2.5 (very acidic)
Other components - water, mucus,
Digestive Enzymes - Pepsinogen, Gastric lipase, prorenin
Gastric juice has various functions :
- HCl present in gastric juice activates inactive enzymes.
- HCl present in juice is bacteriocidal and makes the food soft.
- Rennin present in juice digest Casein which is a milk protein.
- Pepsin digests proteins and gastric lipase converts lipids into fatty acid and glycerol.
