What type of acid is secreted by the gastric pits in stomach?

The gastric pits in the stomach secrete hydrochloric acid (HCl). HCl is a strong acid that helps to break down food in the stomach. It also helps to kill bacteria and other microorganisms that may be present in food. HCl is produced by the parietal cells in the gastric pits. These cells are activated by the hormone gastrin, which is released when food enters the stomach.
