What phase of the gastric secretion is chyme moved into the duodenum?
intestinal phase
What phase or gastric secretion is stimulated by the sight taste and smell of food?
The phase of gastric secretion that is stimulated by the sight, taste, and smell of food is the cephalic phase. This phase involves the brain sending signals to the stomach to start producing gastric juices in anticipation of food arrival.
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.
Nervous control of gastric secretion is provided by what?
The nervous control of gastric secretion is mainly regulated by the enteric nervous system, which is a network of nerves within the walls of the gastrointestinal tract. The vagus nerve also plays a vital role in stimulating gastric secretion, especially during the cephalic phase of digestion when the brain anticipates food. Additionally, hormonal factors like gastrin, produced by the stomach and duodenum, can also influence gastric secretion.
What is cephalic phase of digestion?
it is triggered by the smell, taste, sight, or thought of food. parasympathetic impulses trigger gastric juice secretion.
An example of a gastric secretion is?
HCl (gastric acid), pepsinogen.
Secretion of stomach?
Gastric Acid
What stimulate gastric secretion?
Gastric acid secretion is regulated by hormones in the digestive system. This hormone, gastrin is secreted by the lining of the stomach.
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.
The presence of food in the small intestine A. increase gastric secretion B. inhibit gastric secretion C. has no effect on gastric secretion?
B. Inhibit gastric secretion. When food enters the small intestine, signals are sent to the stomach to reduce the secretion of gastric juices to prevent excessive acid production and aid in the digestion process.
What hormone regulates gastric secretion during the cephalic phase of digestion?
Gastrin, which is secreted by the enteroendocrine cells of the stomach. Gastrin stimulates the secretion of hydrochloric acid and pepsin; induces contraction of the lower oesophagus; mildly increases the motility of the GI tract; and relaxes the pyloric sphincter.
Hormones or paracrines that inhibit gastric secretion include?
Hormones that inhibit gastric secretion include secretin. It is a type of hormone that is released into the bloodstream by the duodenum.
