Malabsorbtion syndromes.
The body cannot absorb nutrients without the correct gastric secretions.
HCl (gastric acid), pepsinogen.
Gastric Acid
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.
Gastric acid secretion is regulated by hormones in the digestive system. This hormone, gastrin is secreted by the lining of the stomach.
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.
Gastric secretion is a normal and necessary process in the body that helps in digesting food. It involves the release of digestive enzymes and acids in the stomach to break down food and facilitate nutrient absorption. However, excessive gastric secretion or imbalances in the stomach acidity can lead to digestive issues like ulcers or acid reflux.
Hormones that inhibit gastric secretion include secretin. It is a type of hormone that is released into the bloodstream by the duodenum.
enterogastric
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.
The component of gastric juice that acts as a hormone to stimulate gastric secretion and movement is gastrin. Released by G cells in the stomach lining, gastrin promotes the secretion of gastric acid (hydrochloric acid) from parietal cells and enhances gastric motility, facilitating digestion. Its release is triggered by the presence of food in the stomach, particularly proteins.
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility
