Esophagus. The esophagus is a hollow muscular tube that connects the back of the throat to the top of the stomach. In an adult, this tube normally ranges from about 10-14 inches in length, and one inch in diameter. At rest, the esophagus is closed but opens readily to accept food and liquids. The muscles in the upper portion of the esophagus are under voluntary control. The remaining portion consists of smooth muscle like the rest of the digestive tract and is not under voluntary control.
