What is the name of the cell that secretes HCI?

Parietal cells
The cell that secrets Hydrochloric acid (HCL) is called PARIETAL CELLS. These cells can be found in the lining of the fundus in the stomach. These cells also make intrinsic factor which is important for the absorption of vitamin B12 in the ileum.

HCL helps create the acid environment in the stomach, and it also helps to destroy bacteria and other harmful organisms. The secretion of HCL from the parietal cells is stimulated by a hormone called GASTRIN. Gastrin is produced by gastric cells (G cells).
Other cell types found in the stomach include:

Mucous cell: this secrets mucus helps to protect the stomach lining from acidic damage.
Chief cell: this secrets pepsin which begins the digestion of protein
G cells: which secrets the hormone gastrin

The name of the cell that secrets HCI is the Parietal cell. These cells are also known as oxyntic or delomorphous cells. The cells are found in the gastric glands that are located in the fundus and the body of the stomach. HCi works as a regulator in the stomach and the gastric system in general. Hydrochloric acid is an essential part of the stomach and the digestive system.

Without it there would not be a balance of acids and neutral fluids. This balance is essential for the human body to work correctly. HCI is a compound of hydrogen and chlorine. Chlorine acts as a gas at room temperature and under pressure.
