(1 point)

bile is released into the duodenum.
saliva and gastrin are released.
the large intestine absorbs water.
the stomach begins to churn.

Explanation:

To determine the correct answer, we analyze each option:

• "Bile is released into the duodenum" occurs during or after food intake, not before.
• "Saliva and gastrin are released" is part of the cephalic phase of digestion, triggered by the sight, smell, or thought of food, preparing the body for digestion before food is eaten.
• "The large intestine absorbs water" happens during the later stages of digestion, not before food is consumed.
• "The stomach begins to churn" typically starts when food is present in the stomach, not before eating.

Answer:

B. Saliva and gastrin are released.
