Answer:
Intestinal
Step-by-step explanation:
Gastric function (secretion) is under the control of nervous and endocrine system. They regulate it by increasing or decreasing gastric secretion and motility. Gastric activity is divided into three stages :
• Cephalic phase-controlled by the brain. This is a phase in which the stomach responds to the mere sight, smell, taste, or thought of food.
• Gastric phase-controlled by stomach itself. This is a phase in which gastric activity is activated by swallowed food and semidigested protein.
• Intestinal phase-controlled by duodenum. This is a phase in which the duodenum responds to chyme that arrived from the stomach and moderates gastric activity through hormones and nervous reflexes.
