Which of the following is NOT contained in the thoracic cavity?

Explanation:
The chest area (the thoracic cavity) is separated from the abdomen by the diaphragm. It contains the heart and lungs, and the esophagus runs through the mediastinum in the chest on its way to the stomach. The stomach, however, sits below the diaphragm in the abdominal cavity. So, under normal anatomy, the stomach is not contained in the thoracic cavity. (Note: in rare conditions like a hiatal hernia, part of the stomach can extend into the chest, but that isn’t the usual location.)
