The thickness of the esophagus varies along its length, but it is typically about 2 to 4 millimeters in adults. The muscular layer of the esophagus is thicker in the lower segment to facilitate the movement of food. The esophagus also has a mucosal layer that contributes to its overall structure and function.

A stomach is attached the esophagus. A pigs anatomy is a lot like a human most people use pigs to understand the human anatomy.
The main function of the esophagus in the human body is to transport food and liquids from the mouth to the stomach through a series of muscle contractions called peristalsis.
The pig and human esophagus differ in several ways, including size, structure, and function. The pig esophagus is generally longer and wider, accommodating the larger size of the animal and its diet, which often includes coarse plant material. Additionally, the muscular layers of the pig's esophagus are more developed to facilitate the movement of food. In contrast, the human esophagus is shorter and has a more uniform diameter, reflecting our different dietary needs and eating habits.

In dogs, this is called "mega-esophagus," a condition in which the muscles of the esophagus are unusually thick and inflexible, so that the animal has trouble swallowing its food. Dogs with this condition require a special diet and a strict feeding routine that requires them to be in an upright position for 20 minutes after eating.
The esophagus is connected to the stomach through a muscular valve called the lower esophageal sphincter. This valve opens to allow food to pass from the esophagus into the stomach and then closes to prevent stomach contents from flowing back up into the esophagus.
