The esophagus is a long, muscular tube that connects your mouth to your stomach. It's around 25cm (10in) long in adults. When you swallow food, the walls of the esophagus squeeze together (contract). This moves the food down the esophagus2 to the stomach

The small intestine (small bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum.
