HUMAN NUTRITION

Detailed explanation-1: -Gastric acid secretion is produced in several steps. Chloride and hydrogen ions are secreted separately from the cytoplasm of parietal cells and mixed in the canaliculi. Gastric acid is then secreted into the lumen of the gastric gland and gradually reaches the main stomach lumen.

Detailed explanation-2: -Gastric juice is made up of water, electrolytes, hydrochloric acid, enzymes, mucus, and intrinsic factor. Hydrochloric acid is a strong acid secreted by the parietal cells, and it lowers your stomach’s pH to around 2.

Detailed explanation-3: -Stomach (gastric) juice is the term used to describe the chemicals that break down food in the stomach. These include hydrochloric acid and an enzyme called pepsin. Gastric juice is sometimes referred to as stomach acid, although not all of the substances it contains are acidic.

Detailed explanation-4: -Gastric secretion is stimulated by the act of eating (cephalic phase) and the arrival of food in the stomach (gastric phase). Arrival of the food in the intestine also controls gastric secretion (intestinal phase). The secreted fluid contains hydrochloric acid, pepsinogen, intrinsic factor, bicarbonate, and mucus.
