The esophagus is a complex part of the body with many cooperative layers which perform different functions. These layers - muscularis mucosa, the submucosa, and the connective tissue - have different structures and textures to aid their activity.

Esophageal cancer is a type of cancer that attacks the esophagus. The esophagus is the muscular tube connecting the throat to the stomach. It is about 10 to 13 inches long. The food you eat needs to pass through the esophagus in order to reach the stomach for further digestion to take place. The esophagus is made up of several layers and cancerous cells usually begin to multiply in the inner layer and grow out to the outer layers. There are two types of esophageal cancer: adenocarcinoma and squamous cell carcinoma.
From the esophagus to the anus, the digestive is basically a tube very similar to other tubular organs in the body. All such tubular organs are composed of several tissue layers arranged around a lumen. In a "generic" tubular organ, these layers are as follows (from the lumen to the ablumenal layer).
Within the stomach and intestines, there are three layers of muscular tissue. These need to withstand high pressures and force the food material through the digestive system. In the esophagus the muscular layer is much thinner. It is also smoother in the esophagus.

The histology changes in each segment of the GI tract, but from the esophagus to anus it has four main layers that vary according to location. They are called the mucosa, the submucosa, muscularis, and serous layers. The real difference is in the small intestine which contains plicae circulares covered with villi and microvilli for absorption of nutrients.
