What is the esophagus?

Transports food: The esophagus is a long tube that pushes food from the throat to the stomach.

Digestive organ: The esophagus starts from the upper esophageal sphincter and ends at the lower esophageal sphincter which empties into the stomach. It is made of striated and smooth muscle.

Tube: The esophagus is the muscular tube that connects the back of the throat to the stomach. The esophagus pushes food along similar to a snake swallowing a golf ball. There are two sphincters in the esophagus, one separating the esophagus from the back of the throat, and a lower sphincter separating the esophagus from the stomach.
