Question

a) Release of gastric juices and enzymes
b) Absorption of nutrients in the small intestine
c) Sight, smell, or thought of food stimulates gastric activity
d) Chyme entering the duodenum

Answer 1

The cephalic phase of gastric control occurs when the sight, smell, or thought of food stimulates gastric activity.

Step-by-step explanation:

The cephalic phase of gastric control occurs when the sight, smell, or thought of food stimulates gastric activity. During this phase, impulses from receptors in the taste buds or nose are relayed to the brain, which then signals an increase in gastric secretion to prepare the stomach for digestion. This phase is relatively brief and takes place before food enters the stomach.
