Stomach

The stomach is a J-shaped organ that is similar to a bag that stretches and moves to churn the food it holds. It is made up of 5 layers of cells that allow it to play out it’s unique functions.

The stomach is attached to the esophagus (the food pipe) on one end and the small bowel on the other. Food enters the body through the mouth. After we chew our food, it passes through the esophagus and then enters the stomach. The stomach then plays its role in digestion before passing the food onwards towards the intestines.

As part of the digestive system, the stomach’s main roles are to hold food and act as a reservoir, release acid and enzymes and mix them with food, and move food through the digestive tract towards the intestines.

The acid and enzymes produced by the stomach are important to support digestion. Stomach acid creates an acidic environment in the stomach that helps to kill off invading pathogens that may be present in our food, thus protecting us against infection. And the enzymes, especially one called pepsin, help by beginning to break down proteins in our food.
