Histamine -amine formed from histidine that stimulates gastric secretions and dilates blood vessels; released by the human immune system during allergic reactions
The hormone gastrin is a powerful stimulant of acid secretion in the stomach. It is secreted by G cells in the stomach lining in response to various stimuli such as the presence of food, caffeine, or stress. Gastrin stimulates the release of hydrochloric acid from parietal cells in the stomach, helping to break down food.
Gastric Acid
Histamine
Fish that have a stomach, generally secrete stomach acid (HCl). However, not all fish have a stomach. For example carp have no stomach and thus no stomach acid secretion.
No, stomach acid is not a histamine. Stomach acid primarily consists of hydrochloric acid (HCl), which aids in digestion. Histamine is a chemical involved in the immune response and regulation of stomach acid production, but it is not the same as stomach acid itself. Histamine can stimulate the secretion of stomach acid from parietal cells in the stomach lining.
Gastric acid
Gastrin is a hormone secreted by the stomach which stimulates the secretion of hydrochloric acid, increase motility, and stomach emptying.
Gastric acid secretion is regulated by hormones in the digestive system. This hormone, gastrin is secreted by the lining of the stomach.
The stomach, particularly the acid that the stomach makes, typically has a pH of around 1 to 2, the lowest of the digestive system.
AnswerCoffee is not bad, research has shown that, in moderation, it can actually be healthy.ANSWERcaffeine hastens secretion of hydrochloric acid in the stomach.
a polypeptide hormone,
Gastric acid secretion can be increased by factors such as the presence of food in the stomach, the release of gastrin hormone, histamine stimulation, certain medications like NSAIDs, stress, and smoking.
