Function Of Esophagus

The esophagus is a muscular tube that carries the food from the back of the throat to the stomach. It must contract in a very coordinated fashion so we don't regurgitate our food or feel that our meals are sticking as we swallow. As well, it is inflammation within the esophagus that gives the sensation of heartburn. The esophagus can be examined through an upper endoscopy or by a cine esophagram
which is a specialized x-ray examination of the esophagus.
