Which of the following statements best describes the major contents of the mediastinum?

Explanation:
The major contents of the mediastinum are the central thoracic structures: the heart and great vessels, the trachea, the esophagus, the thymus, and the associated lymphatics. This central space separates the lungs and their pleural sacs, which are located in the lateral compartments of the thoracic cavity and form the pulmonary apparatus. So, the description that includes the heart and great vessels, trachea, esophagus, thymus, and lymphatics best captures what the mediastinum contains. The lungs and pleura belong to the pulmonary system, not the mediastinal contents.
