What happens when food reaches the stomach?
A
Digestive juices mix with the food.
B
Food is stored, but no digestion occurs.
C
The food is moved into the small intestine.
D
The food is completely digested and absorbed into the bloodstream.
Explanation: 

Detailed explanation-1: -After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.

Detailed explanation-2: -The partially digested food and gastric juice mixture is called chyme. Gastric emptying occurs within two to six hours after a meal. Only a small amount of chyme is released into the small intestine at a time.

Detailed explanation-3: -Gastric juice is made up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins.

Detailed explanation-4: -The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.
