Detailed explanation-1: -Acid that is released into the stomach from glands in the stomach wall. It helps digest food. Gastric acid is made of hydrochloric acid.

Detailed explanation-2: -There are three different types of glands. These glands make digestive enzymes, hydrochloric acid, mucus and bicarbonate.

Detailed explanation-3: -Stomach acid’s low pH level is largely due to hydrochloric acid (HCl). However, there’s only a very small amount of HCl in stomach acid. Other components include potassium chloride (KCl) and sodium chloride (NaCl). The cells lining your stomach wall secrete this acidic trio.

Detailed explanation-4: -Parietal cells in the mucosa, the inner cell layer of our digestive tract, secrete hydrochloric acid (HCl) into the stomach’s lumen, or cavity. The solution in the lumen may have a pH of one or less10 times as acidic as pure lemon juice.

Detailed explanation-5: -Before you go comparing this to what happens in your tummy after eating a Big Mac, keep in mind that sulfuric acid is not as potent as stomach acid, which is a mix of hydrochloric acid, potassium chloride, and sodium chloride. Plus, hydrochloric acid breaks down proteins while sulfuric carbonizes materials.
