Contained within the gastrosplenic ligament. Posterior gastric artery. Celiac ganglion. Vagus nerves. Submucous plexus Meissner plexus. Myenteric plexus Auerbach plexus. Controls inherent myogenic motility of the GIT. Chief cell Pyramid-shaped cells with basally located nuclei and basophilic cytoplasm Contain pepsinogen granules Typically located at the bases of the gastric glands. Parietal cell Large eosinophilic cells with a circular nucleus fried egg appearance Typically located in the middle of the gastric glands.
HCl Intrinsic factor. Ghrelin [2]. D cell. G cell. Thought, smell , and taste of food. ACh vagus nerve. Increase in acid secretion. Distention of the stomach by food. Direct stimulation of parietal cells to secrete gastric acid Stimulation of G cells to secrete gastrin , which stimulates: Parietal cells to secrete more acid directly Enterochromaffin cells to release histamine , which stimulates parietal cells to secrete more acid.
Increases food buffers gastric acid. Acidic chyme containing peptides and lipid metabolites enters duodenum.
Decrease in acid secretion. Helicobacter pylori gastritis. This increase in peptides and amino acids, along with distention from food, further increases HCl secretion. Without adequate HCl secretion, larger fragments of proteins enter the small intestine and may compromise the efficacy of digestive processes.
With good gut health being at the forefront of medicine, would it be realistic to think of adding even more microorganisms to the gastrointestinal tract? The basic premise of an elemental diet is providing nutrition in an easily absorbable form, including all macronutrients: carbohydrates, fats, and protein. The use of zinc-carnosine has been clinically studied for over 20 years, within its origin dating back to Japan.
Ginger and artichoke have been a staple of traditional medicine for centuries. The concept of digestive enzymes is fairly easy to understand, but when delving into the details it is helpful to take a step back and understand what the myriad of available enzymes are actually performing within the body.

Pepsin is a protease, meaning that it cleaves bonds in proteins. It breaks down the proteins in food into individual peptides shorter segments of amino acids. The other enzyme that is active in the stomach is gastric lipase.
This enzyme preferentially cleaves the sn-3 position of triglycerides to produce 1,2-diglyceride and a free fatty acid, as shown below 4. The chyme will then leave the stomach and enter the small intestine via the pyloric sphincter shown below. Brian Lindshield Kansas State University. Belmont, CA: Wadsworth Publishing. Stipanuk MH.
