A Most Excellent Esophagus

I am your esophagus. Some people call me a swallowing tube. I think of myself as the most excellent esophagus. You see, I am very important. If it were not for me, food would have no way to get to your stomach.

I am like a stretchy pipe or tube that is about ten inches long. I have muscles that squeeze from top to bottom to move food into the stomach. My muscles make it possible for you to swallow when you're hanging upside down!
