Abstract

The thoracic cavity houses the essential vascular structures responsible for maintaining systemic and pulmonary circulation. Within this space, the heart and great vessels form a tightly organized anatomical network that ensures continuous blood flow throughout the body. The major blood vessels—the ascending and descending aorta, pulmonary arteries and veins, and the superior and inferior vena cava—occupy distinct yet interdependent positions within the mediastinum. Their spatial relationships to the lungs, trachea, esophagus, and thoracic skeleton are of immense importance for physiological function and clinical practice. A comprehensive understanding of these topographic arrangements is essential for thoracic surgery, radiological interpretation, and management of cardiovascular pathologies. This article describes in detail the three-dimensional organization of the major blood vessels in the human thoracic cavity and discusses their clinical significance.
