Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
What else can I help you with?
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.
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 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.
Demonstrate by experiment the existence of both nervous factor and humoral factor in stimulating the gastric secretion?
The existence of both nervous factor and humoral factor in stimulating the gastric secretion can be demonstrated by the Vagal stimulation of the exocrine pancreas.
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.
What is the parasympathetic and Sympathetic effect on the stomach?
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility
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.
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.
Which of the following is not a phase of gastric secretion?
enterogastric
What controls gastric juice secretion?
gastrin
What is an antisecretory?
An antisecretory is an agent or drug which decreases gastric secretion.
What characteristics does an abnormal gastric acid determination have?
Abnormal findings in the basal gastric secretion test are considered nonspecific and must be evaluated in conjunction with the results of a gastric acid stimulation test. Elevated secretion may suggest different types of ulcers.
The production of gastric juice is an example of what digestive system task?
secretion
