Answer:
The ___________ phase of gastric regulation is initiated when acidic chyme enters the duodenum and stimulates the secretion of hormones and local reflexes that inhibit gastric activity.
a. gastrointestinal
b. cephalic
c. laryngo-pharyngeal
d. voluntary
Step-by-step explanation:
The part of the digestion that is performed in the stomach is called the "gastric phase of digestion."
The food-enzyme mixture that leaves the stomach is called chyme. The movement of the chyme through the pylorus stimulates the intestine to release the hormones secretin and cholecystokinin, which send a signal to the pancreas to release the pancreatic juice inside the lumen of the duodenum, the first segment of the small intestine.
The answer is: a. gastrointestinal.
