The stomach is divided into three compartments namely cardiac, fundus and pylorus. The junction of oesophagus and stomach is guarded by valve which does not allow the food to travel in backward direction.
• In the stomach, food is mixed with the gastric juices secreted by the gastric glands.
• Gastric juice is a combination of hydrochloric acid, enzymes like pepsin, lipase and mucous.
• Partially digested food in the stomach becomes acidic and is known as chyme.
