the stomach. Stomach wall cells, in detail.
The stomach secretes HCL to partially digest the food and to kill any bacteria present in the food.
As protein enters the stomach, it binds to hydrogen ions, which lowers the pH of the stomach to around pH 1-3. Inhibition of gastrin and HCl secretion is lifted. This triggers G cells to release gastrin, which in turn stimulates parietal cells to secrete HCl. HCl release is also triggered by acetylcholine and histamine.
Chief cells of the stomach (gastric glands in stomach have chief cells)
The hormone gastrin functions to increase HCl production in the stomach. Gastric is secreted by G cells.

Parietal cells in the stomach, which secrete HCl
HCl, or Hydorchloric Acid
The normal pH of the stomach is about 2-3 and is caused by a high concentration of HCl secreted by the parietal cells of the stomach.
As protein enters the stomach, it binds to hydrogen ions, which lowers the pH of the stomach to around pH 1-3. Inhibition of gastrin and HCl secretion is lifted. This triggers G cells to release gastrin, which in turn stimulates parietal cells to secrete HCl. HCl release is also triggered by acetylcholine and histamine.
The protease released in the stomach is pepsin. When it is released it's in an inactive form called pepsinogen. Hydrochloric acid (HCL) is also released. HCL actives the pepsinogen to pepsin so it can break down protein. Both HCL and pepsinogen are released from different cells in the glands so they don't combine until they are released into the stomach, this prevents them from eating away the stomach wall. ALSO the stomach secretes a coating of mucus from epithelial cells which helps protect the stomach lining from being digested by pepsin and HCL.

The stomach secretes hydrochloric acid. The acid is produced by special cells called parietal or oxyntic cells. The pH of stomach acid is between 1 - 2. For more details see: http://en.wikipedia.org/wiki/Gastric_acid
The acid in your stomach is HCl with a lowercase L.
Gastrin is a hormone secreted by the stomach which stimulates the secretion of hydrochloric acid, increase motility, and stomach emptying.
