Hydrochloric acid (HCl) is produced in the stomach by specialized cells called parietal cells (also known as oxyntic cells) found in the gastric glands of the stomach lining. This acid creates a highly acidic environment necessary for protein digestion by the enzyme pepsin and for killing ingested microorganisms.
The stomach is the primary organ in the digestive system responsible for producing strong acid.
The oesophagus is a tube connecting the mouth to the stomach. The small intestine is primarily involved in enzymatic digestion and nutrient absorption. The large intestine is mainly involved in water absorption and forming waste.
