Yes but in very small quantities. Gastric acid is the secretion produced in the stomach. It is one of the main ditotonic solutions secreted, together with several enzymes and intrinsic factors. Chemically it is an acid solution with a pH of 1 to 2 in the stomach lumen, consisting mainly of hydrochloric acid (HCl) (around 0.5%, or 5000 parts per million), and large quantities of potassium chloride (KCl) and sodium chloride (NaCl).
What else can I help you with?
What secrete hydrochloric acid?
Gastric glands in the stomach secrete hydrochloric acid. This acidic environment helps break down food and kill bacteria that may be present in the stomach.
What secrete hydrochloric acid into the stomach?
The presence of food may trigger release of gastric acid, which is the hydrochloric acid. This in turn activates the inactive protein pepsinogen into pepsin.
What cells secrete hydrochloric acid?
Chief cells lining the stomach. (They actually secrete H+ and Cl- ions individually, but it becomes HCl in the solution).
Where in the digestion system do pepsin and hydrochloric acid begin the splitting of the proteins?
In the Stomach. The first part of digestion is chewing in the mouth and mixing with saliva. Then swallowing. THen when in the stomach, the stomach walls naturally secrete hydrochloric acid and pepsin into the 'mix'. The stomach operates at pH = 1. This is a natural process, and you DO NOT swallow hydrochloric acid.
Why is the stomach lining undamaged by hydrochloric acid?
The stomach lining is protected by a thick layer of mucus that acts as a physical barrier against the corrosive effects of hydrochloric acid. Additionally, the stomach lining has specialized cells that secrete bicarbonate to neutralize the acid and maintain the optimal pH for digestion. Lastly, the stomach lining has a rapid cell turnover rate, constantly regenerating and repairing itself to prevent damage from the acid.

What secrete hydrochloric acid into the stomach?
The presence of food may trigger release of gastric acid, which is the hydrochloric acid. This in turn activates the inactive protein pepsinogen into pepsin.
The secretory parietal cells of the stomach are responsible for producing?
The parietal cells of the stomach secrete hydrogen ions and chloride ions, which combine to form hydrochloric acid.
What are the types of secretory cells in the stomach and what do they secrete?
Gastric glands which secrete:HClRenninpepsin
What are the secretory parietal cells responsible for?
They secrete Hydrochloric acid in the stomach to help break down peptides.
Which of the cells of the stomach secrete hydrochloric acid and the intrinsic factor?
The cells of the stomach that secrete hydrochloric acid (HCl) and intrinsic factor are called parietal cells, or oxyntic cells. These specialized epithelial cells are primarily located in the gastric glands of the fundus and body of the stomach. Hydrochloric acid aids in digestion and creates an acidic environment, while intrinsic factor is essential for the absorption of vitamin B12 in the intestines.
Why does walls of the stomach secrete hydrochloric acids?
Hydrochloric acid is secreted from the stomach because the enzyme pepsin, which breaks down proteins in the stomach, works best in acidic conditions. The acid also helps to kill any bacteria in the food. The hydrochloric acid is actually secreted from the pits in the stomach wall called gastric pits.
Can stomach acid dissolve organs?
stomach acid is HCL (hydrochloric acid) and can dissolve organic matter (organs).The acid is required to synthesise fats .However the linings of the wall secrete a mucus to protect the stomach wall
What is the function of Parietal cell?
Parietal cells are found in the lining of the stomach and secrete hydrochloric acid and intrinsic factor. Hydrochloric acid helps with digestion by breaking down food and killing bacteria, while intrinsic factor is important for the absorption of vitamin B12 in the small intestine.
What cells secrete hydrochloric acid?
Chief cells lining the stomach. (They actually secrete H+ and Cl- ions individually, but it becomes HCl in the solution).
