2. Gastric acid - Wikipedia

   en.wikipedia.org/wiki/Gastric_acid

   The lowest pH of the secreted acid is 0.8, [5] but the acid is diluted in the stomach lumen to a pH of between 1 and 3. There is a small continuous basal secretion of gastric acid between meals of usually less than 10 mEq/hour. [6] There are three phases in the secretion of gastric acid which increase the secretion rate in order to digest a ...

3. Phases of digestion - Wikipedia

   en.wikipedia.org/wiki/Phases_of_digestion

   50-60% of total gastric acid secretion occurs during this phase. The gastric phase is a period in which swallowed food and semidigested protein (peptides and amino acids) activate gastric activity. Ingested food stimulates gastric activity in two ways: by stretching the stomach and by gastric contents stimulating receptors in the stomach. [2]

   Its anti-inflammatory nature could help quell excess acid production. A 2023 study found that four weeks of ginger supplementation significantly reduced stomach pain, burning, and heartburn in 51 ...

5. Gastrointestinal physiology - Wikipedia

   en.wikipedia.org/wiki/Gastrointestinal_physiology

   Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract.The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products.

6. Gastrin - Wikipedia

   en.wikipedia.org/wiki/Gastrin

   Gastrin is a linear peptide hormone produced by G cells of the duodenum and in the pyloric antrum of the stomach.It is secreted into the bloodstream. The encoded polypeptide is preprogastrin, which is cleaved by enzymes in posttranslational modification to produce progastrin (an intermediate, inactive precursor) and then gastrin in various forms, primarily the following three:

7. Parietal cell - Wikipedia

   en.wikipedia.org/wiki/Parietal_cell

   A canaliculus is an adaptation found on gastric parietal cells. It is a deep infolding, or little channel, which serves to increase the surface area, e.g. for secretion. The parietal cell membrane is dynamic; the numbers of canaliculi rise and fall according to secretory n

8. Hydrogen potassium ATPase - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_potassium_ATPase

   The gastric hydrogen potassium ATPase or H + /K + ATPase is the proton pump of the stomach.It exchanges potassium from the intestinal lumen with cytoplasmic hydronium [2] and is the enzyme primarily responsible for the acidification of the stomach contents and the activation of the digestive enzyme pepsin [3] (see gastric acid).

9. Digestive enzyme - Wikipedia

   en.wikipedia.org/wiki/Digestive_enzyme

   The enzymes that are secreted in the stomach are gastric enzymes. The stomach plays a major role in digestion, both in a mechanical sense by mixing and crushing the food, and also in an enzymatic sense, by digesting it. The following are enzymes produced by the stomach and their respective function: Pepsin is the main gastric enzyme.
