Acid chyme stimulates the duodenal wall to secrete what?

the gland cells secrete mucus, which neutralises the acidity of the chyme produced by the stomach

Acid chyme is a fluid mixture of food and gastric juices.

The duodenum has special glands, Brunner's glands, that secrete an alkaline fluid to counteract the acidity of the chyme from the stomach which uses hydrochloric acid as part of its digestion of proteins.

Gastrin stimulates gastric acid secretion in the stomach.

Chyme is a liquid - food churn in the stomach in the presence of Hydrochloric Acid which has a pH of 2.0. Therefore Chyme has a pH of about 2.0

Bicarbonate is the secretion that neutralizes stomach acid as chyme enters the small intestine. Bicarbonate is necessary because chyme is highly acidic. Bicarbonate is created in the pancreas.

Your gastric cavity or stomach

because of it low pH(making it acidic), the duodenum (the first section of the small intestine) secretes cholecystokinin (CCK), which causes the gallbladder to secrete bile.

Hydrochloric acid and pepsin

chyme Pronounced (cyme)

Secretion of bicarbonate from epithelial cells is considered to be the primary mechanism by which the duodenal mucosa is protected from acid related injury.

The statement that bicarbonate is released into the duodenum during the process of digestion is true. The Brunner glands in the duodenum secrete mucus that contains sodium bicarbonate which neutralizes the acid in chyme thereby protecting the duodenum.

reflux of acid chyme from the stomach into the lower esophagus

When the hydrochloric acid in the stomach breaks down the food.

Insects excrete uric acid as a metabolic residue.

When chyme first enters the duodenum from the stomach, it is acidic because of the gastric acid. Once in the duodenum, the chyme is exposed to pancreatic and brunner gland secretions which contain bicarbonate. The bicarbonate changes the pH of the chyme to neutral or slightly basic because the small intestine does not have the same protections against the hydrochloric acid as the stomach. Thus, the answer is that chyme becomes more basic as it…

These are the two types of secretory cells in the stomach. Parietal cells- secrete hydrochloric acid Chief cells- secrete pepsinogen

Pancreatic fluids break down fats, carbohydrates, and proteins in the chyme.

Ulcers are cause by Hydrochloric Acid (HCl) and pepsin which can be found inside our stomach and duodenal parts of our digestive system.

gastric acid and intrinsic factor

Gastric chief cells (as opposed to the chief cells present in the parathyroid gland) are the zymogen cells in the stomach that release pepsinogen (a precursor (zymogen) of pepsin). Without stimulation chief cells normally secrete pepsinogen at about 20% of the maximum ability. ACh (released by nerves) is the most important pathway for gastric chief cell activation. ACh also stimulates parietal cells, which secrete HCl (stomach acid). The fall in pH causes a reflex which…

Brown sugar does not contain uric acid but it stimulates the production of uric acid by the body.
