Vagus Nerve and Enteric Plexus.
Demonstrate by experiment the existence of both nervous factor and humoral factor in stimulating the gastric secretion?

What gland is found in the mucosa of the small intestine and produces intestinal juice?

Select the correct statement about the regulation of gastric secretion?
ANSWER IS: Gastric secretion can be stimulated before food has entered the mouth.A.Gastric secretion can be stimulated before food has entered the mouth.B.Gastric secretion is enhanced by very low pH (below a pH of 2)C.The presence of food in the stomach prevents hormonal control of gastric secretion.D.Vagus stimulation of the stomach results in decreased secretion of gastric juice.
What is the intestinal phase?
control of gastroc secretion is divided to cephalic phase, gastric phase and intestinal phase. Among these, intestinal phase means gastric secretion in stomach as a result of stimulation in intestine by food. when the food reaches the intestine it secrete gastrin and the hormone transports to stomach by circulation. amount of secretion in intestinal phase is smaller and slower than that of cephalic and gastric phase. by the way if substance like acid, lipid or any high osmotic solution entered intestine, duodenum, gastric secretion decreases this time. This is because of enterogastrone released from duodenum. there are also other hormones such as cholecystokinin and gastric inhibitory peptide. they inhibit the secretion in stomach.
What is gastric acid determination?
Gastric acid determination, also known as stomach acid determination, gastric analysis, or basal gastric secretion, is a procedure to evaluate gastric (stomach) function. The test specifically determines the presence of gastric acid, as well.

HCl (gastric acid), pepsinogen.
What are the typical responses to ingestion in the gastrointestinal tract?
