The walls of your stomach.
the walls of the stomach is alkaline and the food contain in the stomach is acidic.. it will not accept the nutrients to enter inside the stomach walls. the small intestine having villa in the walls and it ll absorb the nutrients in the food.
The movement of the walls of the stomach is accomplished by a group of smooth muscle that undergoes what is called peristaltic action.
because of the mucus like substance on the stomach walls.
Hormones do not have anything to do with a grumbling stomach. The stomach walls are lined with muscle that contracts and expands all on it's own. Any food and liquids in the stomach cause grumbling noises as the stomach walls expand and contract.
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.

an ulcer
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
cardiac muscle walls of the stomach and intestines walls of blood vessels
No, that's the stomach. The esophagus is a hollow tube with muscular walls.
the chemicals in the stomach are there to break down the food that enters, there are certain chemicals that stop the acid in the stomach burning the stomach walls and infecting your body.
mucus protects your stomach from the acid
