Email Article. Esophagus. The esophagus is a small hose-like tube, which connects the mouth to the stomach. As it leaves the mouth, the esophagus follows a straight path through the neck and chest, passing near the heart through the diaphragm muscle and finally entering the stomach.
If the mouth is the gateway to the body, then the esophagus is a highway for food and drink to travel along to make it to the stomach. This body part has a very simple function, but can have many disorders. The esophagus is a tube that connects the throat (pharynx) and the stomach. It is about 8 inches (20 centimeters) long. The esophagus isnât just a hollow tube that food slips down like a water slide, though. The esophagus is made of muscles that contract to move food to the stomach.
