Esophagus — This muscular tube is located dorsal to the trachea. Food is pushed forward in the esophagus by the rhythmic contractions of its walls in a process known as peristalsis.
The esophagus extends posteriorly and dorsally within the thorax, then passes through the diaphragm into the abdominal cavity where it ends at the stomach
In order to find the esophagus use a probe to move the diaphragm away from the heart towards the abdominal cavity. Then with a pair of scissors, cut the left and right edges of the diaphragm slightly, just enough for you to completely pull it away from heart. Then gently use your probe to left the heart slightly to expose the esophagus underneath.
To view it from the abdominal cavity, locate the stomach and move the diaphragm up towards the heart. Then to the left corner of the stomach towards the liver and up against the diaphragm, you should be able to view the connection point of the esophagus to the stomach.
