Gastric glands The gastric glands are located in different regions of the stomach. These are the fundic glands, the cardiac glands, and the pyloric glands. The glands are found in the gastric pits of the stomach lining.The various cells of the glands secrete mucus, pepsinogen, hydrochloric acid, intrinsic factor, gastrin, histamine and bicarbonate.he cardiac glands are found in the cardia of the stomach which is the part nearest to the heart, enclosing the opening where the oesophagus joins to the stomach. Only cardiac glands are found here and they primarily secrete mucus.

Digestive 5 Much of this is through the stimulation of the Vagus nerve. Impulses arriving from the Vagus to the gastric glands stimulates the release of gastric juice (exocrine) and the secretion of gastrin (endocrine). The gastrin being a hormone, enters the blood stream and is carried back around to the stomach.

- Pepsin is the chief digestive enzyme in the stomach that breaks down proteins. We see that chief cells produce pepsinogen (an inactive form of pepsin). Pepsinogen is converted to pepsin when the parietal cells found within the gastric glands secrete hydrochloric acid.ucus that is produced by the epithelial cells of the stomach help protect the lining of the stomach from the corrosive hydrochloric acid and pepsin. If this protective lining fails, it can result in a peptic ulcer, which is a lesion of the mucosa.

- Home » Gastrointestinal Medicine » GI Physiology » GI Secretion » Gastric Secretion. Stomach acid is secreted by parietal cells located within oxyntic glands of the stomach. The primary purpose of stomach acid is to lower the pH of the gastric contents sufficiently to allow activation of pepsinogen to pepsin.

Anatomy of the Endocrine System Digestive System: The hormones cholecystokinin (CCK), secretin, and gastrin are all produced by the organs of the gastrointestinal tract. CCK, secretin, and gastrin all help to regulate the secretion of pancreatic juice, bile, and gastric juice in response to the presence of food in the stomach.

The Two Types of Exocrine Secretory Cells in the Stomach The stomach is an organ of the digestive system. The inner wall of the stomach contains small pores called gastric pits. These pits contain cells that secrete chemicals that digest food. The two main types of exocrine secretory cells of the stomach are parietal cells and chief cells.Parietal cells secrete hydrochloric acid and chief cells secrete digestive enzymes such as pepsin.These cells secrete their products when activated by signals from the body such as hormones and neurotransmitters.hief Cells. The other type of exocrine secretory cell in the stomach is the chief cell. Chief cells secrete digestive enzymes that cleave the proteins in food into smaller pieces. The main enzyme secreted by chief cells is pepsin. Pepsin is secreted as an inactive enzyme called pepsinogen.

Gastric glands Fundic glands found in the fundus and also in the body have another two cell types–gastric chief cells and parietal cells (oxyntic)). The chief cells are found in the basal regions of the gland and release a zymogen – pepsinogen, a precursor to pepsin. The parietal cells (parietal means relating to a wall), are found in the walls of the tubes.

- Gastrin is a hormone found in the human body that regulates the secretion of digestive acid, and is produced by cells in the lining of the stomach. Testing for gastrin may help to discover diseases like pernicious anemia. Several blood samples will be taken from a patient in order to test for gastrin.

The Anatomy of Digestion Gastric juice is a high acidic mixture of hydrochloric acid, enzymes, and mucus that begins chemical digestion and sterilizes the stomach. It is secreted by glands located in the middle portion of the stomach that secrete an average of 2,000 to 2,500 ml (which is 8.5 -10.5 cups) of gastric juice a day.igestion is a series of physical and chemical changes by which food taken into the body undergoes hydrolysis (addition of water) and is broken down in preparation for absorption from the digestive tract into the bloodstream.

- The stomach is the part of the GI tract which contains hydrochloric acid. Hydrochloric acid is made by the stomach's parietal cells, secreted into the stomach's lumen, where …it has an acidic pH around 2-3, which is very acidic (roughtly the same as neat lemon juice). Hydrochloric acid and pepsin (an acid protease), cooperate in digesting proteins.

Ice Cream Or Gelato? Whatâs The Difference? What About Calories? Economy brands usually have the least amount of fat and super premium brands have more. Milk fat content of less than 10% makes the product ice milk or light ice cream. Premium ice cream has between 11% and 15% butterfat, which makes it richer, denser, higher in calories. It often comes in gourmet flavors.

- Digestive system. Gastric glands are composed of epithelial cells (A), chief cells (C), and parietal cells (B). The chief and parietal cells produce and secrete mucus (D) to protect the lining of the stomach (F) against the harsh pH of stomach acid. The mucus is basic, while the stomach acid (E) is acidic.
