Meet GI Guy

GI Guy illustrates the organs that are part of the digestive system, including the mouth, esophagus, stomach, small intestine, the colon (large intestine), the rectum and anus. Gastroenterologists also treat organs that aid in the digestive process, like the liver, pancreas and gallbladder.

To find out more about the digestive system, simply move your mouse over GI Guy and click on a specific organ. You will find links to more information about the diseases we treat and the procedures we perform at Atlanta Gastroenterology Associates.

Esophagus

The esophagus is a tube that connects the throat to the stomach. When you swallow, muscles in the esophagus help push food down to the stomach.

Liver

The liver helps with digestion by processing fats and cholesterol. It is also critical in ridding the body of drugs and other toxins and plays an important role in maintaining proper blood chemistry.

Stomach

After you have chewed and swallowed, the stomach is where the next phase of digestion occurs. Here muscles in the stomach wall and acid-producing glands break down food before it enters the small intestine.

Colon (Large Intestine)

After nutrients are absorbed in the small intestine, food moves into the large intestine, where water is absorbed. What is left after this process is completed is solid waste (or fecal matter), which will be eliminated from the body.

Small Intestine

After food has been liquefied in the stomach, it moves into the small intestine. The small intestine is where nutrients are absorbed in to the body.
