Hydrochloric acid is secreted from the stomach because the enzyme pepsin, which breaks down proteins in the stomach, works best in acidic conditions.
The acid also helps to kill any bacteria in the food.
The hydrochloric acid is actually secreted from the pits in the stomach wall called gastric pits.

What does the walls of the stomach contain?
The walls of the stomach contain a thick layer of mucus. The stomach itself is filled with pepsin and Hydrochloric acid in order to digest food. The thick layer of mucus prevents these acids from digesting the wall of your stomach. Occasionally this mucus recedes and some of the acid can get in. When this occurs, it causes a Peptic Ulcer.
What lines the walls of the stomach to prevent hydrochloric acid from damaging tissues?
mucus protects your stomach from the acid
What protects your stomach walls from acid?
A lining of mucus is what protects ur stomach from hydrochloric acid
What is acid-reflux and how does it feel?
Acid reflux is when stomach acids rise into the esophagus and burn the walls. The stomach can bear the harsh acids because the stomach is lined with walls that protect the other organs. Some people get ulcers which are holes in the stomach's lining (very painful) :( If the stomach acids make their way too far to the top of the esophagus the walls of the esophagus are burned because they do not have protective lining walls mostly because acid is not meant to be there! :) hope this helped
What churns food and adds gastric juices and acids?
stomach walls

What does the protease do?
Gastric protrease is produced by the walls of the stomach. It breaks down proteins to amino acids in the stomach (a highly acidic place).
How does the stomach protect it self from being digested?
a simple way of answering this question would be that the stomach creates it's own acid that almost makes a protective layer on the inside of the stomach. this stops bad germs and diseases that come in through food/water from eating away at the stomach.
What prevents pepsin from destroying the cell walls in the stomach?
Pepsin is secreted as pepsinogen. Pepsinogen cannot eat the walls of the stomach. Now, pepsin is formed when pepsinogen binds to the hydrochloric acid (HCl) in the stomach. Once they are binded pepsin is formed. The second reason on why the stomach doesn't eat it's self is because of the alkaline mucus that suround the walls of the stomach.
If you did not have mucus would your stomach digest itself?
Sort of. The mucus lining in your stomach prevents the acids that digest food from eating away the walls of your stomach. Once you have a hole in your stomach, the acids would then leak out and start eating away at your internal organs. An ulcer is an indication this is starting to happen.

How does hydrochloric acid in the stomach work considering that it is highly corrosive?
The lining of the stomach is made up of thick tendons and cell walls which are strong enough to support acids of up to PH 2. However, if this wall were to slightly break, then an ulcer would form, preventing the acid to damage any vital organs.
